Hi again,
At http://matplotlib.sourceforge.net/installing.html under topic OS X:
"All of the backends run on OS X. Chris Barker has built a binary package (fink users see below) for matplotlib which is hosted on pythonmac, and works with Agg, Wx and Tk; see the step-by-step instructions kindly provided by Michael Tobis."
note that the step-by-step link leads to:
Under revision. Please come back soon.

It is because I've had some installation troubles that I have been looking at the OS X install info so closely.
For instance: originally I tried to use macports for all python site-packages-related installs (as well as using their python24). The ONLY backend that seems to work thru that route is WxAgg (http://howdy.physics.nyu.edu/index.php/Numpy_For_Mac_Using_MacPython corroborates this). I was able to achieve results w/backend WxAgg and numerix Numeric. However, when I tried to change the toolbar to classic, WxAgg crapped out.
W/MacPorts, I've been able to get the TkAgg backend to work, but _NOT_ with numerix set to Numeric. Success was only achieved w/TkAgg when numerix was set to Numpy. When I try the WXAgg backend (along w/the pythonmac 2.6.3.3 wxPython dmg for python 2.4), a simple plot([1,2,3]) craps out with:
