It seems I've gotten exactly as far as you have--segfault after the
splash screen.  I assume you also had to install "py26-wxpython +gtk"
from MacPorts, as I did.  Also, there are some other #ifdef __WXMAC__
instances that should probably be changed to #ifdef __APPLE__, though
some of them are probably still legitimate.  I've started a ticket at
https://code.ros.org/trac/ros-pkg/ticket/4852.

I'm very curious as to whether you're getting the same error as I am on launch:

objc[16512]: Class OgreView is implemented in both
/Users/vernaza/ros/visualization_common/ogre/ogre/lib/Ogre.framework/Versions/1.7.1/Ogre
and /Users/vernaza/ros/visualization_common/ogre/ogre/lib/RenderSystem_GL.dylib.
One of the two will be used. Which one is undefined.

Whatever that means, it certainly sounds like it needs to be fixed.
Finally, my backtrace follows for reference:
