The current ebuild uses a binary package, but the DEPEND do not specify emul libraries for amd64. They are often installed on standard amd64 installations, but it's better if the dependency is there Needed emul packages are: app-emulation/emul-linux-x86-baselibs app-emulation/emul-linux-x86-sdl app-emulation/emul-linux-x86-soundlibs app-emulation/emul-linux-x86-xlibs Pulling in emul-linux-x86-sdl pulls the other ones as dependencies, so adding a conditional DEPEND on emul-linux-x86-sdl is enough. On a side note, files get installed into /usr/games/lib64, which is not well suited for a 32bit binary game package
dependencies and the path-issue fixed and the package is masked on no-multilib profiles now, thanks
