That is what I am now trying.

I am trying to build a ppc64 version.  I don't have a Core 2 Duo Mac :-(

It seems to have all the bits and will build a fortran hello world in  
ppc64 using -m64.   However, the libraries are in /usr/local/lib/ 
ppc64 which seems to confuse the configure script and causes a  
failure in the attempt to link C and Fortran code.  I will try to  
lipo the ppc64 libraries into the ppc ones in /usr/local/lib.  Is  
that what you meant?
