I'm surprised that you were building profiling libraries, that's not 
normally part of validate.  Did you do a plain 'make'?

hmm, I don't see that here:

$ /usr/bin/time make FAST=YES stage2/build/libHSghc-7.1.20101008_p.a
...
3.59user 1.10system 0:05.16elapsed 90%CPU (0avgtext+0avgdata 
97376maxresident)k 0inputs+519016outputs (0major+120732minor)pagefaults 
0swaps


Anyway, I suggest not building the profiling libraries if you don't need 
them.
