Issue when building with macos

[hoaknoppix]

It returns as follow when executing pip install -r requirements.txt:

cdnarules.c:281:14: error: incompatible integer to pointer conversion returning 'int' from a function with result type 'PyObject *' (aka 'struct _object *') [-Wint-conversion]
return PyErr_BadArgument();
^~~~~~~~~~~~~~~~~~~
1 warning and 1 error generated.
error: command '/usr/bin/clang' failed with exit code 1

Please help to double check, and I also feel like if it comes to this statement on Mac, there is something not right as well for this guard:
if (!PyArg_ParseTuple(args, "O!O!", &PyArray_Type, &X, &PyArray_Type, &Y)) {
return PyErr_BadArgument();
}

it should not come to the return statement.
