[GRASS-dev] wxversion checking does not work with bundled wxpython

[William Kyngesburye]

I was looking into the possibility of bundling a slimmed-down wxpython  
into the OSX application package and ran into a problem.  It appears  
that wxversion.select() does not work with a bundled wxpython.  From  
the wxversion docstring:

   NOTE: If you are making a 'bundle' of your application with a tool
   like py2exe then you should *not* use the wxversion module since it
   looks at the filesystem for the directories on sys.path, it will fail
   in a bundled environment.  Instead you should simply ensure that the
   version of wxPython that you want is found by default on the sys.path
   when making the bundled version by setting PYTHONPATH.  Then that
   version will be included in your bundle and your app will work as
   expected.

I suggest changing the CheckForWx() line in globalvar.py, and a bunch  
of others, to:

if not os.getenv("GRASS_WXBUNDLED"):
     CheckForWx()

Then I can set PYTHONPATH and GRASS_WXBUNDLED and the wx gui will use  
the bundled wxpython.  (tested and it works)
