I had to build matplotlib and many of its requirements in my home
directory because I lack privileges to put stuff in /usr/local. So I
build python-2.6.2, freetype-2.3.9, numpy-1.3.0, tcl-8.5.7, tk-8.5.7,
and matplotlib-0.98.5.3. Each of those is in its own subdirectory in /
home/gam/packages.
Since these packages are not in /usr/local, I had to alter pathways in
certain cases in order to get stuff to build, link, and work together.
Things seem close to working, but matplotlib is unable to load a
backend (_tkagg). Here's what happens:
1655: python
Python 2.6.2 (r262:71600, Aug 5 2009, 09:48:28)
[GCC 3.4.6 20060404 (Red Hat 3.4.6-11)] on linux2

If I understand correctly, _tkagg corresponds to _tkagg.so. Python
ought to be able to load that object if it's in python's search path.
The output above shows the presence of site_packages in sys.path, and
that site-packages/matplotlib/backends/backend_tkagg.py does get
loaded. _tkagg.so is in the same directory, as shown here:
1654: ls /home/gam/packages/Python-2.6.2/lib/python2.6/site-packages/

I have tried clean rebuilds and reinstalls from the ground up but end
with the same result.
Help!
Thanks.
