Not surprisingly, recompiling from source did not fix my problem.  
Phenix (and python) run fine on several computers with PAE kernels in  
the lab. So, it seems to me that this is likely a processor/chipset  
issue more than a kernel problem. The only differences between the  
machines that work and the one that doesn't is the hardware.
