For future reference, when on OS X, it's very helpful to include how
you installed your Python, and whether it's 32-bit or 64-bit.

I believe you've installed 32-bit libraries for a 64-bit Python (or
possibly vice-versa). It appears that NumPy & SciPy official releases
are 32-bit-only. So, you can either use the alternate, unofficial
64-bit releases of those packages, or install a 32-bit Python (via
Fink, MacPorts, a Python.org installer, etc.). A third option is to
install the Enthought Python Distribution
(http://www.enthought.com/products/epd.php ) or similar, which bundles
Python together with SciPy, NumPy, and other libraries in a single
install.

Cheers,
Chris
