[Numpy-discussion] First steps with f2py and first problems...

[LB]

    Hi,

I've tried to follow the example given at :
http://www.scipy.org/Cookbook/Theoretical_Ecology/Hastings_and_Powell
but I've got errors when compiling the fortran file :

I'm using debian testing, and I got the following information at the
bottom of `f2py -h` :

numpy Version: 1.0.4
Requires:    Python 2.3 or higher.
License:     NumPy license (see LICENSE.txt in the NumPy source code)


Have you got any clue to solve this pb ?
