Did you install wxPython? Did Macports?

I understand how MacPorts works in this regard. Fink does the same  
thing, though you can opt not to install dependencies and can also  
install binaries that might need the dependencies (i.e., only needed  
to compile). This is a Linux-like package installer model. It is handy  
but can have problems playing nicely with other unix software  
installed on your system outside of the MacPorts (or Fink) package  
hierarchy. I know that both try to wall off their stuff into separate  
areas, but sometimes it doesn't work.

To try and overcome the complications of having more than one Python  
version and more than one wxPython version, both William and I now  
include a wxPython build in our GRASS binaries. However, I'm not sure  
what will happen in a situation like yours. Hopefully my binary will  
work.

You might need to search out and look at your various system  
configuration files and see if any of them refer to the MacPorts  
Python. These normally live in your home folder and the etc folder.  
They begin with a ".", so are invisible unless you run something like  
Invisibility Toggler.app, use Text Wrangler's open hidden function, or  
use the command line utilties.

Files to look for include .profile and .bashrc. There might be others  
too depending on how MacPorts manages setting system configurations.
