Hello,
I used your new beta installer to install matplotlib on a G5 running OS X 10.5.5. I tried the contour demo and got this error
pylab_examples$ pythonw contour_demo.py
Traceback (most recent call last):

I was able to build matplotlib by using MACOSX_DEPLOYMENT_TARGET. I built libpng 1.2.33, freetype 2.3.7 and pkgconfig 0.23 with gcc 4.0.1 from XCode 3.1.2. to build and install matplotlib I did
env MACOSX_DEPLOYMENT_TARGET=10.5 python setup.py build
sudo env MACOSX_DEPLOYMENT_TARGET=10.5 python setup.py install
I don't get "Symbol not found:" errors for _png.so now, but negative signs on numbers in the axis labels appear as boxes instead of -'s. I may try the freetype in /usr/X11 instead of the one I compiled.
Thanks for all the work on matplotlib,
Scott
