Yes, but I took care to not confuse them.

I found that:

"To prevent loading extension modules that assume a 32-bit size type into an
interpreter that has a 64-bit size type, Py_InitModule4 is renamed to
Py_InitModule4_64." (http://www.python.org/dev/peps/pep-0353/)

So as numpy's setup.py cannot call 'Py_InitModule4' this means, that the
interpreter is built for 64bit systems. Maybe numpy is more accurate in testing
wether it run's on 64 or on 32 bit than the python build script itself and
therefore expect's Py_InitModule4 to be present.

Isn't there perhaps a configure option to force 32 bit?
