Hi Darren,
Yes, unfrotunately I tried this as well to no avail.
Thank you though,
Frank

Try removing the build/ directory from your mpl source directory, as well as 
your site-packages/matplotlib*, and recompile.

Thanks so much for the response, Mike. Yes, I learned the hard way a
long time ago about having to rm -rf build/ when rebuilding python
packages. I have tried this here, but I still have an issue. I am
currently trying to rebuild with a different compiler and playing with
environment variables. I would love any other suggestions. Thanks,
Frank

I don't know if this will help, but...
Python packages generally don't have proper dependency management when 
building. That means, if an underlying dependency changes, it often 
doesn't rebuild enough to keep things in sync. You may want to try 
rebuilding everything after first completely removing the "build" 
directory to force a complete rebuild. Do numpy first then matplotlib.
...but maybe you've tried that already, in which case, I don't know off 
hand...

Hi,
I am sorry to bug you all with an installation problem, but I need
some additional help to get this figured out.
I previously had a matplotlib installed and working fine, but it was
necessary for me to redo some other installations like numpy when I
needed a complete lapack library. This also led to me installing
another version of g77, because numpy needed a specific library that
was only provide by the g77 version of fortran for some reason.
Anyways, numpy works great but I went back to install matplotlib and I
ran into trouble. After the installation process, if I try to import
matplotlib.pylab I get the following errors:
from matplotlib._path import affine_transform
ImportError: /ronaldo/pkg/dfranci/gcc-g77-3.4.6/lib64/libgcc_s.so.1:
version `GCC_4.2.0' not found (required by /usr/lib64/libstdc++.so.6)
Is this a problem that I can fix in the matplotlib installation or do
I need to go back up to the numpy installation?
I should note that I do not have gcc-4.2.0 on my system.
Thanks in advance,
Frank

Great. Does this mean we can close the bug?

Hi, folks!
I am trying to compile matplotlib-0.98.3 on OSX 10.5.5. with support
for the native port of GTK-2.0 (www.gtk-osx.org). I am doing this
because the official egg gives an error when my GUIs try to create a
canvas using GTK (with all renderers: GDK, Agg or Cairo). I assume the
official egg was compiled without support for GTK on OSX.
I compiled GTK-2.0 and PyGTK using code and instructions from Imendio,
and it all works fine. The apps I developed on a Ubuintu system run
fine on OSX, except for the matplotlib part.
So, all the libraries and headers are installed in the default
folders. However, when I try to build matplotlib I get the following
error:

error: command 'gcc' failed with exit status 1
However, gtk.h and pygtk.h are in the folders where I believe they
should be (/usr/include/gtk-2.0/gtk and /usr/include/pygtk-2.0/pygtk).
I ran throught the code of check_for_gtk included in setupext.py, and
the only thing I found out of order was that the line
get_pkgconfig(module, 'pygtk-2.0 gtk+-2.0') should read
get_pkgconfig(module, 'pygtk-2.0 gtk-2.0'), as the installation folder
of GTK is gtk-2.0 and not gtk+-2.0. However, I changed this line and
got exactly the same error.
Has anyone successfully compiled matplotlib with support for the
native port of GTK for OSX? Could somenoe help me getting it compiled?
Thanks in advance,
