blender ebuild fails on ppc, as build is x86 specific, with x86 binary as part of ebuild.
It seems that blender downlaods have been temporarily disabled (see http://www.blender.nl/download/index.php), so we can't retreive the ppc version (yet)
Already keyworded out on PPC. Will look again when/if blender is available again. Keyworded this out on all other archs as well.
working on the ebuild for blender.org blender
Blender source build in CVS. If interested, give it a shot.
