Hi Numpy users! 

I maintain the boundary value problem solver package scikits.bvp_solver. It's had problems with f2py for a while, and I am not sure where they are coming from. I made this stackoverflow post some time ago, but I didn't get any solutions.

Here are the details: 

I am trying to update my package scikits.bvp_solver (source here) and I have run into some problems with f2py generated files. The files 'bvp_solverf-f2pywrappers2.f90' and 'bvp_solverfmodule.c' which were generated in 2009 allow the package to be built in place with "python setup.py build_ext --inplace" but if I delete them and try to rebuild I get the error

scikits/bvp_solver/lib/bvp_solverf-f2pywrappers2.f90:218.48:

use guess_3_wrap__user__routines
1
Fatal Error: Can't open module file 'guess_3_wrap__user__routines.mod' for reading at (1): No such file or directory
scikits/bvp_solver/lib/bvp_solverf-f2pywrappers2.f90:11.19:

The file bvp_interface.pyf specifies a python module guess_3_wrap__user__routines, but I do not see this show up in the f2py generated modules.

The part the adds this use statement does not appear in the old version of the file. I am having difficulty figuring out how to fix this issue. Can anyone offer advice? What are the major changes to f2py in the last two years? 

I appreciate all clues on this issue.

Thank you in advance,
John
