Steve: I cannot reproduce this error. It would help if you sent a
self-contained example that I can run to trigger the error. It is
puzzling since the line that the traceback is pointing to is in a
try/except block which tries to old matplotlib API to set the color of
the map boundary, and if that fails use the newer 'spines' module (which
is available in 1.0). My hypothesis is that you somehow have a mixture
of old and new matplotlib versions installed in
/usr/lib/python2.5/site-packages, but that's just a guess.
