[f2py] OS X 10.4.9 Mac intel and gfortran - has anyone gotten this to work?

I am running Python 2.5, Numeric 23.1 on an OS X 10.4.9 MacPro intel.
( the Numeric version is used for compatibility to a rather large and  
vital legacy code not in my control)
I installed gfortran for the intel Mac from hpc.sourceforge.net.
I installed scipy_distutils-0.3.3_33.572 and F2PY-2.45.241_1926.

The python was built using GCC 4.0.1 (Apple Computer, Inc. build 5363).

When I try to run f2py I get the errors at the bottom of this  
messge.  A number of undefined references, apparently from the python  
interface.
Going through the archives I have seen that this error has been  
encountered before - but I could not discern any definite resolution  
to the problem. I could just be dense.

One suggested solution is to use gcc 3.3 and g77 - it appears that  
gcc 4 and g77 are not  compatible.  Although the test code is f77,  
this solution does not solve my f90/f95 code problems.

So is gfortran a viable option for OS X 10.4 and f2py? Or should I  
try to get my boss to spring for Intel Fortran?
