Well the bad memory theory seems out the door. I downloaded memtest86 
and ran it for a couple of hours with no errors.  I did a fresh install 
of R5F27 but still see the seg faults duing 'make'.

I tried the ./config command you suggested above and it ran for quite 
awhile but still finished with a 'internal compiler error: Segmentation 
fault'.

And uname -p returns 'unknown'

My proc/cpuinfo output looks like:
processor   :  0
vendor_id   : GenuineIntel
cpu family   : 6
model          : 15
model name   : Intel(R) Core(TM)2 CPU         6400 @ 2.13GHz
stepping   : 6
cpu MHz   : 2131.321
cache size    : 2048 KB
