It is indeed true that I have gcc 4.0i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1
(Apple Inc. build 5490)

I installed it using a pre-compiled binary for OS X Leopard, so I did not set
any options. Perhaps I should build from source and add this option?

That is true... I do have Macports installed and /opt/ is for Macports. But for
Python, Numpy, and Scipy, I used the pre-compiled binaries for OS X; the
matplotlib I am trying to install now is from the subversion repository. I am
not sure what you mean by the initial diagnostic output (perhaps output
below?), but I used make.osx and specified that zlib, png and freetype be
installed in my ~/dev directory as shown in README.osx and make.osx. I also
added all the paths recursively to my PATH in case it was using this variable
to look for these programs, but my output error still looks like
basedirlist is:

Sorry for my delayed response - I am currently on travel... but I hope this is
fixable. If nothing else comes to mind, I will try installing Python 2.6 from
source with the option you mentioned?
Thanks so much!Stephen
