By default setuptools (distribute) installs packages as eggs, and
loading eggs requires the ability to write a .pth file to a directory
that will be checked for .pth files at start up (i.e. is in PYTHONPATH
or otherwise on sys.path by default). You can avoid doing an
egg-based install by instead running:
python setup.py install --single-version-externally-managed --prefix
/usr/local/stow/matplotlib-1.3.0
or something to that effect. I think if you do this you also need to
make sure to manually add the .egg-info directory as well. I think
you can do this with
python setup.py install_egg_info --install-dir
/usr/local/stow/matplotlib-1.3.0/lib/python2.7/site-packages/
but YMMV. You might also try just installing with pip since it will
basically install the package in the same way by default.
