[Gentoo] Pegasos gets some exercise

I’ve started using the Pegasos as a tinderbox for X.Org — take a look. It’s spyder-ppc-6_8 for now, because it’s building what will become the 6.8.2 release in the next week or two. After that, it’ll start following CVS HEAD again. I had it set up as a tinderbox a while back and caught a few build errors in the one or two nights I had it running — I’m hoping to continue this trend to keep X working well on PPC.
