After some hunting and digging I solved this.  After upgrading Python 2.5.1
which comes in OS X 10.5 to Python 2.5.4, all is well.

I found this out in a roundabout way....first I got it working after
realizing the path was off when the App fired up.  The libraries were ending
up in

dist/plot_in_wx_test.app/Contents/Resources/lib/python2.5/

which wasn't in sys.path.  What *was* in sys.path was:

dist/plot_in_wx_test.app/Contents/Resources/lib/python2.5/site-packages

After a little hackery I got it working.  Then I realized that Python wasn't
being included in the build so upgraded to 2.5.4 (which wasn't as simple as
I hoped).  After that, the build worked no problem.  Hopefully this will be
useful to someone else.
