Created attachment 370192 [details, diff] allegro-5.0.8-r1.ebuild.patch This patch adds proper (non emul-linux) dependencies for media-libs/allegro, removing dependencies on emul-linux-x86-{opengl,sdl,soundlibs} for a multilib build. Tested with ABI_X86="32 64". There's still a dependency on emul-linux-x86-gtklibs because GTK+ isn't converted to multilib yet.
Seems to have been fixed at some point.
