G'day,

this solved the original problem, but there is new trouble on the 
horizon which appears to be caused by the f2c package see below:

 File "/usr/pkg/lib/python2.5/site-packages/numpy/linalg/linalg.py", 
line 29, in <module>
    from numpy.linalg import lapack_lite
ImportError: /usr/pkg/lib/libF77.so.0: Undefined PLT symbol "MAIN__" 
(symnum = 164)

This what I found in the f2c "readme" file:
<quote>
libf77  Library of non I/O support routines the generated C may 
need. Fortran main programs result in a C function named MAIN__ 
that is meant to be invoked by the main() in libf77.
