# emerge -p tuxracer These are the packages that I would merge, in order. Calculating dependencies ...done! [ebuild R ] x11-base/xfree-4.2.0-r12 to / [ebuild N ] media-libs/smpeg-0.4.4-r2 to / [ebuild N ] media-libs/sdl-mixer-1.2.4 to / [ebuild N ] app-games/tuxracer-0.61-r1 to / Obviously, xfree shouldn't be replaced. Also add support to only upgrade to the latest version of a package that matches the same slot of one of the installed versions.
Fixed in 2.0.18
