[Gentoo] Overlay in layman

I just added my Portage overlay to layman. It’s got a few live git/cvs ebuilds for X-related things including xorg-server, some video drivers, mesa, xgl, compiz, cairo, glitz. I try to keep them as vanilla as possible and ready to go into the main tree, which distinguishes this from other overlays.

Also it’s got a bunch of biochemistry-related software that I use in my day job but isn’t yet ready for the main tree, and the Sun Studio compilers (but the IDE itself doesn’t work yet).
