David,
I'm not aware of any compatibility problems when using WxMpl with MPL
0.91, but then again I can't remember if I ever tested it thoroughly.
Could you please send me a short script that reproduces the problem,
along with the complete error message it generates? Thanks.

OK, finally had cause to work on this some more. With Chris Barker's help:
0) Tried unsuccessfully to reproduce the problem in a "minimal" app.
(i.e., quoting Chris: "it's difficult to build a minimal app. which
reproduces the problem");
1) We kluged a fix by manually adding get_xdata and get_ydata methods to
our derived class, but a) this seems like it shouldn't be necessary, and
b) it wasn't necessary before;
2) Chris' hypothesis is that it has something to do w/ the work being
done on matplotlib to add units to data objects (please correct me if
I'm wrong, Chris) but is uncertain of precisely how or why, and wasn't
readily able to pin it down more than that;
3) We're both rather amazed that no one else has yet reported this
problem, suggesting that either a) we don't scan posts to this list
carefully enough :-), or b) there's perhaps something wrong w/ my
installation?
Bottom line: working, but w/ an "unsatisfactory" solution.

Additional info: when I'm in the directory in which wxmpl.pyc resides
inside the py2app bundle, run Python and import wxmpl, I get:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "wxmpl.pyc", line 18, in <module>
(
File "wx/__init__.pyc", line 45, in <module>
File "wx/_core.pyc", line 4, in <module>
File "wx/_core_.pyc", line 18, in <module>
File "wx/_core_.pyc", line 15, in __load
ImportError:
'/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/wx/_core_.so'
not found
(Note that the application package from which I got this error is the
version of the program that works!)
Following a suggestion, I copied this wxmpl.pyc to a place outside the
application package, ran python, and it imported fine. I checked its
version number and it's 1.2.8, same as what I have installed presently
(wxmpl.__file__ verified that the local version was imported, not my
site-packages version).
I'm at more of a loss than ever...
