Barry, it is quite hard and hacky to get f2py working in the general case.
I think the email from Gaetan in this thread proves my point.

IMHO, it is easier to write a small Fortran source exposing the API to call
using ISO_C_BINDINGS, then wrap that code with the more traditional C-based
"static" tools (SWIG, Cython) or even "dynamically" with ctypes or cffi
(which use dlopen'ing).
