I'll answer my own question. It was a mix of using two different fortran
compilers so specified the option: python setup.py config_fc
--fcompiler=gfortran build.
All seems to be going well now.

That actually makes sense because I am not sure the gnu that it was
compiled with but I think it is different. I have since compiled gcc
myself, then python, and atlas libraries. Then I tried to install
numpy. It go tthrough the install no worries and found the correct
libraries. It stuffed when I tried to import it with this error:

Any ideas???

Python is looking for a 64-bit library as the one in
/usr/local/lib/ is
either 32-bit or built with a different compiler version. If you have
the correct library in another location then you need to point
numpy to
it or just build everything with the same compiler.
