Hi David,
Good to hear you've had some luck with rviz on the Mac, and thanks for
documenting it a bit. Some comments below...

Unfortunately, I dug around a bit with gdb, and the problem I was
having is deeper than that. Basically, wx-gtk was giving Ogre an X
window to render in, when it expected a native window, which does not
work at all. More info here:

This is the major problem, unfortunately. Everything breaks going to
64-bit. It is worth noting, though, that it is possible to manually
boot OS X 10.6 into the 32-bit kernel:
http://support.apple.com/kb/HT3773. So, if people are really
desperate for rviz on the Mac, I guess that's one option.

It's a bug in the package:
