It sounds to me as if you need import_array. Without this,
gistC is unable to access the functions in _numpymodule. (In
general, .so files can't access eqach other's symbols.)

What you need, right before the assignment to PyOS_InputHook,
is

#ifdef import_array
   import_array()
#endif

This should fix the problem.
