[Alug] Gentoo questions..

Hi Folks After installing RH8.0 over the weekend and getting really (and I mean *really) **** off with yet another compiler producing broken binaries, I think it's about time to look at another linux base. Some questions for the Gentoo experts (cos gentoo.org times out on me). Do I need an existing linux install as I would with Linux From Scratch ? What compiler does it use ? Does the gentoo CD come with sources for useable desktop environments such as KDE ? How long would it take to build a working system (complete with X and KDE) on a Duron 800MHz box ? Regards, Paul.
