Here is an ebuild for ScummVM v0.3.0b, which is a crossplatform interpreter for the classic Lucasarts adventures. I added many features to this ebuild compared to the old 0.2.0-r1 one... This one respects the use-flags "oggvorbis alsa sdl mpeg opengl". The old one only checked "sdl". The X11 backend is broken in this release, so when/if a new release comes out with it fixed, we should just add sdl as an optional dependancy (attn: the opengl-backend also requires sdl!) and uncomment the 'eerror "X11 is broken"' section..
