the installation package for OS-X is for the python.org build -- from 
the above, I can see you are running Apple's python, which came with a 
version of numpy.

I don't remember how you installed matplotlib, but in general, most 
extrenal packages are built for the python or python, so what I wold do is:

download and install python 2.5.2 from python.org (2.6 is brand new, and 
not yet well supported by external packages)

re-install numpy 1.2.0 (may not be necessary, but it won't hurt)

re-install MPL.

you can tell what python you are running by typing "python" n the 
command line -- it should be 2.5.2 if it's the python.org one. If that's 
not what you get, you may need to edit your .bash_profile file to add it 
to your PATH.
