Yes, me (again).
Maybe this is a processor issue, but for an Intel P4, I only can repeat: if you
have installed gcc4/gfortran and no other compiler, following the installation
instructions for ATLAS on the wiki building scipy _is_ straightforward. You
won't need any additional information, even building ATLAS with full is covered
there.

You could also try to force to use gfortran like this:

python setup.py config_fc --fcompiler=g95 build

Regards, Christian

ps: I can provide numpy/scipy rpms for SuSE10 with ATLAS built on that processor:
