2 issues: 1. 3.14.0-defaults.patch does not apply 2. if the bad patch is commented out the build fails when it cannot find libmutter-clutter.so.1 This is because it is not in the ldcache after building mutter. running ldconfig /usr/lib64/mutter fixed the issue. I assume this is a problem in the mutter ebuild
