Mmm, I can compile and run the example just fine. That's strange because
your Pyrex error seems to tell that NPY_MAXDIMS is a Python object
instead of an integer. But in my numpy installation, NPY_MAXDIMS is
defined in ndarrayobject.h, which should be imported automatically by
Pyrex in:

cdef extern from "numpy/arrayobject.h":

block (which should include ndarrayobject.h).

Sorry for not being able to help more,
