It works in the most recent MMTK version (2.0), but it didn't work
in some earlier versions when used with newer releases of NumPy.

I recommend upgrading to the most recent versions, but if you want to
go on with what you have, replace the function init_surface in the
file _surface.c by this one:

init_surface()
{
  PyObject *m;

  /* Create the module and add the functions */
  m = Py_InitModule("_surface", surface_methods);
  
  /* Import the array module */
#ifdef import_array
  import_array();
#endif

  /* Check for errors */
  if (PyErr_Occurred())
    Py_FatalError("can't initialize module _surface");
}

I suppose that in your copy the line "import_array();" is missing, and
that causes an immediate crash with sufficiently new NumPy versions.

BTW, a better place for such questions is the MMTK mailing list!

Konrad.
