Follow directions here to install/use meta-repo.
Funtoo eliminated stable.
Funtoo users running stable have to upgrade to current.
I had one system running stable that I upgraded to current while still running ports-2012 before switching to meta-repo.
Funtoo in many cases upgrades package versions at a slower rate than gentoo.

(0) 1.0.2k^d {M}(~)1.1.0e(0/1.1)^d

Curly brackets { } around the Mask  =>  {M}
The version was originally masked in $PORTDIR/profiles/package.mask, but this was locally changed in /etc/portage/package.unmask.
Eix indicates you have manually unmasked openssl-1.1.0e in /etc/portage/package.unmask
Remove that configuration.

The conversion to meta-repo from ports-2012 downgrades xorg-server from 1.19.1_p20170228 to 1.17.4-r1
You manually removed xorg-server-1.19.1_p20170228 which was being replaced with xorg-server-1.17.4-r1
Due to the file collision you haven't finished installing x11-base/xorg-server-1.17.4-r1
 
I had the same file collision error that prevented xorg-server from updating.
# mv /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/10-evdev.conf~ No file collision after rename, install of xorg-server-1.17.4-r1 should succeed.
Before starting Xorg check for /usr/share/X11/xorg.conf.d/10-evdev.conf
If you start xorg-server without 10-evdev.conf the mouse won't move the cursor.
On my system it didn't exist, I rename 10-evdev.conf~ back to 10-evdev.conf
# mv /usr/share/X11/xorg.conf.d/10-evdev.conf~ /usr/share/X11/xorg.conf.d/10-evdev.conf After the update is finished:

Updated stable and current funtoo are running python2.7.12 and python3.4.5
The python-exec configuration was not updated and is still pointing to python3.3 which is no longer on your system.
Open a terminal, as root user:
eselect python edit At the bottom of the text delete python3.3
Save and exit.

Type this command and hit Enter:
eselect python list You should see:
