OK, just nuked the box. Did a reformat and newly install of CentOS 4.1. No 
changes to the BIOS or mem timings or anything. Now I am able to compile.

Guess it wasn't a timing problem. The box was horribly slow too, tarring 
and gzipping 600 mb took about 2 hours. The box has been on the internet 
without a firewall for approx 30 minutes, could it be r00ted that quick?
