The ebuild contains many dependencies that are not used by the package. I have verified that these libs aren't needed, but there are probably more: media-libs/game-music-emu media-libs/libbluray media-libs/openjpeg:0/5 media-libs/schroedinger media-libs/zvbi media-sound/twolame x11-libs/libva x11-libs/libvdpau
not in betagarden anymore
