vkraven got a reaction from linuxbigot in btrfs install...
Some googling tells me that's a Sandy Bridge CPU. I'm not completely certain, however, if intel64-sandybridge will work since the wiki page does say Core i3/5/7, although I can't think of any reason why it shouldn't.
Should you want to play it a little safer though, you could go with corei7.
vkraven got a reaction from dad in Circular Dependency problem
I got that issue today too. Was this other package jsoncpp?
I got around it by emerging an older version of cmake, cmake-184.108.40.206, then emerging jsoncpp, and updating cmake to current.
To have portage emerge the older version, try echo ">dev-util/cmake-220.127.116.11" >> /etc/portage/package.mask
Once that's done, I removed the line from package.mask
Hope it works for you!
