When performing an emerge --update --newuse --deep @world -pv, I get this error: emerge: there are no ebuilds built with USE flags to satisfy "x11-libs/libX11[xcb]". !!! One of the following packages is required to complete your request: - x11-libs/libX11-1.4.3 (Missing IUSE: xcb) - x11-libs/libX11-1.4.1 (Missing IUSE: xcb) (dependency required by "x11-wm/compiz-0.8.6" [installed]) (dependency required by "x11-wm/emerald-0.8.4-r1" [installed]) (dependency required by "x11-themes/emerald-themes-0.5.2" [installed]) However the xcb use flag does not exist for the libX11 package. Reproducible: Always Steps to Reproduce: 1. Install compiz-fusion 2. emerge --update --newuse --deep @world -pv 3. Actual Results: Emerge --update --newuse --deep @world fails complaining about an use flag that does not exist. Expected Results: The x11-libs/libX11 should have a "xcb" use flag associated with it.
Given that 0.8.6 ebuild was removed about three months ago... If you're mixing, check your package.keywords.
