If you're going to install wxWindows into /usr/local then there's no
real reason to follow the directions for the private wx, but it should
still work like this...

Thanks. I'll get this fixed.

I've just tried exactly what you did above on my Mandrake 8.2 system
with Python 2.2 and it works fine.
One possibility -- since the wxPython build gets its compiler flags and
etc. from Python's build via distutils -- is that there is some flag
conflicting with wxGTK's build that has changed with Python 2.3. I'd be
interested in seeing a copy of a compile commandline for one of the
sources from the wxGTK build and another one from the wxPython build.
Another possibility is that it may be fixed simply by disabling rtti
and/or exceptions in the wxGTK build. You can try adding the following
flags and then rebuilding all of wxGTK and wxPython:
RTTI and exceptions are not needed by wxPython so I guess I should
probably add them to the "Private wxGTK" instructions anyway as there
should be a bit of a performance boost...
