After world update, i've to uninstall all compiz packages, but then wanted to bring them back, and... # emerge compiz-fusion -pv These are the packages that would be merged, in order: Calculating dependencies... done! [ebuild N ] x11-plugins/compiz-plugins-unsupported-0.8.4-r1 0 kB [ebuild R ] x11-wm/compiz-fusion-0.8.6 USE="emerald gnome unsupported* -kde" 0 kB Total: 2 packages (1 new, 1 reinstall), Size of downloads: 0 kB Complete build log: http://pastebin.com/yex0FVkY Emerge info: http://pastebin.com/cmTn0t13
The bug has been addresed here: http://bugs.gentoo.org/show_bug.cgi?id=289450 For some reason it doesn't appear in the internal search, but luckily found by googling. It worked for me.
Seems that this does not happened with recent compiz ebuilds, so closing as FIXED
