I'll look through my logs more closely, but at quick glance it doesn't 
look like any problems occur until it tries to link.  I have no problems 
using 1.2.5, but this is a different machine (in fact I don't have 
access to the other OS X machine I previously compiled 1.2.5 on), so I 
figured I'd start with the latest source, since I have to compile anyway 
(plus 1.2.6 was supposed to have better OS X build support).

I probably will try MPICH2  as well.
