True! But all of these demos do run for me. I suggest you flush your
existing matplotlib by removing site-packages/matplotlib and your
"build" directory and reinstall from the official source at
http://sourceforge.net/project/showfiles.php?group_id=80706&package_id=82474&release_id=281218.
Please follow the instructions at
http://matplotlib.sourceforge.net/installing.html, eg make sure you
have numeric or numarray installed when you compile matplotlib.

Let us know if you have more troubles, and please include a full
traceback from one of the date demos and run it with

python date_demo1.py --verbose-helpful

and report the output.

It's a distutils thing. Suggestions here welcome.

After a bit of pondering and one false start (one compile failed because
it could not find some item related to GTK) I got matplotlib compiled for
the Tkinter backend only. It is the only one I'm interested in right now
anyway.

An update to the .matplotlibrc file solved the problem of seeking the GTKAgg
backend which was not there and we were off to the races. All of the date
examples completed without a hitch. A quite gratifying result! Apparently
the Debian package I downloaded had some problems.

One of the biggest challenges was translating short forms of software names
into the package names used on the Debian package site-just one of those
realities of the great world of open-source software. Not everyone uses
the same descriptive name for the same entity.
