I ended up disabling all methods in minpack_module_methods[]
except "_chkder" in _minpackmodule.c

In __minpack.h, I commented out everything, except
for minpack_chker(). In this function I had to comment out
the two calls to CHKDER().

Without the calls to CHKDER() importing succeeds and
with the calls it fails.

So, it looks like if there is something wrong with
calling Fortran from C in this module.

If there is nothing wrong with the compiler/linker flags
produced by setup.py, there is something wrong with
Mandrake's gcc/g77-2.96.

Travis, did you use the standard Mandrake gcc & g77?
