I successfully built Python 2.7.2, NumPy 1.61, and Scipy 0.9.0 in my home
directory on a Centos5 system. I am trying to build matplotlib 1.0.1 in my
home directory, but I am having a problem with the GTK backends. I also built
pycairo 1.2.2, pygobject 2.14.2, and pygtk 2.10.6 in my home directory (using
the libraries and headers installed in the default system locations). I
downloaded a few pygtk examples from the tutorial section of their web site and
ran them to verify that pygtk works correctly.
Here is the error I get when I run a script that contains only the line "import
matplotlib.pyplot":

Here is the beginning of my matplotlib build log, which shows that the build
process is actually finding the GTK libraries:
basedirlist is: ['/home/cfinch']

------------ SNIP -----------
There are no errors in the build or install logs, but I can post the rest of it
if necessary. Also, the library _backend_gdk.so is present in
~/lib/python2.7/site-packages/matplotlib/backends/.
Any suggestions would be appreciated!
