Sometime in October, Christopher Barker proposed the following: 

| 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.

Thanks Chris,

This worked great. Along with the above mentioned stuff, I also  had a bit
of trouble installing the MPL egg which seems to be mac specific.  This was
also pretty useful in fixing that:


The important part being: 
  That said, the build on the matplotlib website is self-sufficient save  
  for numpy, use the -N flag to easy_install (and don't forget to run it  
  with sudo). This should take care of things.
