This information might be useful for tracking down the problem. Namely, it
is possible scipy_distutils that comes with F2PY is a bit older than the
latest scipy_distutils and therefore lacking some bits regarding to
Windoza stuff. I suggest that you update scipy_distutils from
www.scipy.org (you need to get it from its CVS repository).

That said, I looked at the scipy CVS and found that mingw32-support
needs lib2def but that is part of the weave package. So, as a quick fix,
get lib2def.py file from the scipy/weave directory and put it into
the f2py2e/scipy_distutils directory and reinstall f2py. This should solve
your problem, I hope.

Well, there is always SWIG, Pyfort, manual wrapping.
