I was able to build numpy/scipy using gcc4.0.2.

Summary : GNU Fortran 77 Compiler
This is a Fortran 77 only compiler based on GCC 3.3.5. It can be used
for source not yet compilable by the gcc-fortran package which contains
the new gfortran compiler.
So I have used g77 to compile ATLAS and numpy/scipy. It works fine for me.
Essentially gfortran cannot be used !!!!
