I have no idea why, but for some reason the ebuild considers OPENGL as an "optional dependancy". Best quick fix would be to `USE="opengl" emerge lablgl`. Hopefully the ebuild mantainer will notice this and patch it up.
Jan, can you give me the compilation trace ? Chris, i suppose you tried 0.99 or older ? I fixed that in CVS.

Fixed in CVS. The real problem was that even if you did not have the glut flag set, the -lglut compiler flag was set and it would fail even if nothing used glut. Thanks for reminding me of this bug :)
