I was curious how much space it needed, so I wanted to keep everything.

No I didn't. That's the reason why glibc failed. I didn't have prelink.

noarch packages were built. To get the count of unbuilt packages, I 
compared the .src.rpm list before and after compiling.

This was on my work desktop.

You should take a look at ccache http://ccache.samba.org/
I'm sure that helped a bit.
If you have a cluster of machines, look at http://distcc.samba.org/

Both are cool tools.

eh, howto's imply I know what I'm doing ;)
