If  "<dev-util/gdbus-codegen-2.48.2" is blocking dev-libs/glib-2.48.2,
then try to emerge gdbus-codegen-2.48.2 and glib-2.48.2 in one command:
funtoo rj # emerge -1av =dev-util/gdbus-codegen-2.48.2 =dev-libs/glib-2.48.2 These are the packages that would be merged, in order: Calculating dependencies... done!

Hi!
SElinux mix-in now enabled in Funtoo Linux profile. 
http://www.funtoo.org/News:Selinux_Support
Thx to Ryan Decker for his mix-in and SElinux testing.

Sync and update the system and eix database.
Check eix for latest current version of qbittorrent.

The error message in your first post:

you don't need to run update of use-local-desc. it's in included in portage tree. But real problem in your case was missing --repo=gentoo

Try
 
# emerge --regen  
If You've an active software firewall ... try to disable it temporarily.

Sandro: 
Thanks for idea with irc channel, I will join soon.
If we are talking about backup app I dont care what its will be. My goal is to make start point of my fresh funtoo instalation(doing everthing again is suicide :) ). I was trying kbackup (after finish copying files he was finishing for few hours (teoretycy he was comperssing so I left it for night but it didnt finish so I cancel it and everything was gone), then obnam - I didnt see he was finish - just stop in some moment :/. Im ready to try all available apps to make my start point. If u guys can advise me simple automatic(perfect I would be if I dont have to choose folderst to dont miss something important) backup app to make my start point I will be grateful. I was thinking about mondorescue or filezilla but I have windows and funtoo lvm encrypted system on 1.8TB disk - can I make a live dvd with it?
cardinal:
I recompile libsecret    with +vala +introspection USE flags and emerge deja-dup with no problems :) thanks for that. After years with debian stable funtoo/portage world is very new and weird :P

If You use KDE:
Try (as root):
# egencache --update-use-local-desc # euse -E wxwidgets -p app-arch/p7zip # emerge -DNu p7zip (if you want the "complete 'tree') or # emerge -Nu p7zip If You want You can enable the USE flag "wxwidgets" also in make.conf as "Global USE flag"
 
Please, tell us if solved or not :)
 
Otherwise I think may be a good thing to post your "epro list".
 
If You don't use kde, you can try with
# USE="-kde" emerge -u p7zip Then mask it in /etc/portage/package.use
 
eg: (# euse -D kde -p app-arch/p7zip).
 
Hello :)
 
(Dobr?nos) _'_ :)

this should work on both. however this looked as git corruption.

maybe a git tree got corrupted. yes, it's perfectly safe to remove the tree and then do initial emerge --sync (or eix sync), it will clone fresh copy of portage tree.

# eselect python set 3 # env-update && . /etc/profile # python-updater # perl-cleaner --modules # revdep-rebuild # emerge -DNu world --with-bdeps=y # emerge -c # emerge firefox Try that way .... if You want _'_
 
If this method doesn't run, post your
cat /var/lib/portage/world  
cat /etc/portage/make.conf  
If the portage requires "emerge @preserved-rebuild", simply make:
# emerge @preserved-rebuild

Happy I could help :)

sandro, i think you are missing the point on pstate driver.
 
when i use i7z, it may show frequency maxed out at 3.9GHz, but c1 state shows 97 percent of processor is in halt state.
 
isn't that power saving?
 
for a long time i had microcode enabled in kernel and would see in dmesg something about microcode driver. 
 
i assumed it was working but there is more too it.
 
i use git-sources. i use method two from this page
https://fitzcarraldoblog.wordpress.com/2014/11/06/updating-intel-cpu-microcode-from-gentoo-linux/

Hi to all; I've 2 systems:
1) PC Desktop with cpu intel 4771, nVidia GTX 660, 16 GiB ram. 
2) An old laptop "Acer" con cpu Athlon 64x2 @ 1,9 GHz, Radeon HD 3200, 3 GiB Ram.
 
 
With PC "1" i use plasma-5 without troubles with "GLX" with nvidia-drivers.
 
With the laptop, using "glx" i've graphical errors; instead if I use "egl" all seems to work fine.
 
But ... what is the best choiche ?
 
"glx" or "egl" ?
 
Thanx for answers :)

Martin considered EGL as the default, see https://blog.martin-graesslin.com/blog/2015/08/should-we-target-egl-as-the-default/. I don't think it is easy to say which is the best choice, only for you it is clear cut since the graphics error answer  that ;)

Excuse me for third post .....
 
I've used boinc (that for me is the software which for me it is the most resource-hungry and also it raises more than anything else the temperatures of the cores) to test the 2 situations:
 
1) with Intel P-state enabled in kernel , with MATE DE, I obtain ~4300 for Weathston (fpu) per core and only ~ 10500 in Integer (Drystone). :o
2) Without Intel P-state fpu (Whetstone) is similar, but in integer (Dhrystone) is near 15000 MIPS per core
 
Then for this moment the choice is to use cpupower without P-state driver.
 
But that discussion is ever opened ..... Who knows what will happen in the future ?
 
Hi to All & great Dear whiteghost :)

I have an Intel i7-4770K and I use the kernel CPU Frequency scaling options without pstates and it works fine.  I set the default governor to "ondemand" in the kernel.  Each core then idles at 800MHz and scales up as needed.
 
I have cpupower installed on my system, but don't really need it as the kernel settings do what I desire.

i added cpupower to default runlevel with this line in conf.d
 START_OPTS="--governor powersave -d 1000MHz -u 2000MHz"
and it works.

Every 5.0s: cat /proc/cpuinfo | grep "MHz"                                                                      Fri Jul 15 18:43:12 2016
 
cpu MHz         : 3899.902
cpu MHz         : 3900.329
cpu MHz         : 3899.902
cpu MHz         : 3900.115
 
 
look at documentation - /usr/src/linux/Documentation/cpu-freq/
 
i disable acpi driver enable pstate and powersave gov and pstate works automatically.  googling pstate - it gets too technical for me.
i use cpupower frequency info and cpupower frequency set

analyzing CPU 0:

  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 800 MHz - 3.90 GHz
  available cpufreq governors: performance powersave
  current policy: frequency should be within 800 MHz and 3.90 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
  current CPU frequency: 895 MHz (asserted by call to hardware)
  boost state support:
    Supported: yes

i do not have cpupower added to rc
