This is happening because Leopard comes with an older version of numpy  
already installed in:
/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/ 
python

I'm pretty sure that this searched in before the path where your numpy  
install is. This issue has come up before in many places, here's one:

I'm not sure what the current "best practice" is thought to be. You  
should be able to change your PYTHONPATH environment variable to load  
the correct directory first.

Some suggest to install your own (newer) version of python from  
python.org for your own use and leave the system python for Apple's  
use. You can then easily install the numpy/scipy/matplotlib/ipython  
tools with the "Scipy superpack" installer:

An easier route might be to use the enthought distribution (if their  
licensing is OK with you):

It installs its on Python framework in:
"/Library/Frameworks/Python.framework/Versions/2.5.2001"

And numpy,scipy,ipython,matplotlib all just work out of the box.
