Re: compiling problems w/ py2.6 on OS 10.4

matplotlib 0.98.3 predates the release of Python 2.6, so it is 
unsupported in that combination.  There were recent changes made to 
matplotlib in SVN to make it (more) Python 2.6 compatible.  You may run 
into further trouble trying to get it to work with Python 2.6

That, however, doesn't seem to be the root of your compilation problem.

src/backend_agg.cpp:3:17: error: png.h: No such file or directory

...indicates that it can not find the headers for libpng.  Did you 
follow the instructions here:

http://ipython.scipy.org/moin/Py4Science/InstallationOSX

...particularly regarding installing pkgconfig?

If not, let us know where your libpng is installed.  You can try, as a 
hack, adding that directory to the list of the darwin directories at the 
top of setupext.py.

Cheers,
Mike
