[f2py] f2py and windows

I followed the simple instructions at http://www.scipy.org/F2PY_Windows and tried to make
a Python module from my f95 code with the result of the following error message: " Value
error: invalid version number '2.18.50.20080109' ". Similar problems have been registered
elsewhere too, but I'm still not sure what to do. I understood that the problem might be in the f2py source code..?

I have Python2.5.1, numpy-1.0.3, gfortran (dated 2009-04-21).

MinGW-5.1.4 was installed earlier (though the site above does not istruct to install
MinGW. Is it needed or not..?)

Thank you in advance,
Johanna Torppa
