I now bundle wxPython in my binary distribution, to avoid confusion if  
a user has installed another version.  Also Apple's version is a bit  
old now, though it satisfies the minimum version GRASS needs.  For  
those building GRASS from source, an up-to-date version of wxPython  
can be installed and used with the system Python.

Another thing I just added in RC5 and SVN (for the OSX app build) is  
the ability to attempt to use a version of Python that wxPython is  
built for.  This only works for when wxPython in bundled in the app,  
and is hardwired (requires editing grass.sh.in in the macosx app  
source).  This helps for GRASS distributions (like mine) where a user  
might have other Python versions installed that may cause trouble.

I also now include an up-to-date version of numpy in my GDAL framework  
(it's used there also).  The system version is a very old 1.0.1, and  
GRASS requirements say at least 1.0.4.

The equator is so long, it could encircle the earth completely once.
