It would be cool if you could add x11-themes/skulpture to the portage tree. It's a nice and fast KDE4 style. I've tested the ebuild from http://skulpture.maxiom.de/releases/skulpture-0.2.3.ebuild and I had no issues yet. Reproducible: Always
Forgot to mention: I had no issues with this ebuild on ~amd64 using gcc-4.3.3, glibc-2.10.1-r0 and kernel 2.6.29-gentoo-r1
Yup, done. Enjoy. (sync in ~1h and it will be on your favorite mirror close to you :P)
Wow, that was FAST! Thanks :-)
