Yeah, I just noticed a another oddity in init.sh related to wx - the  
gui dependency test is still based on X.  While wxpython on other  
'nix platforms may need X, it doesn't on OSX, and probably not on  
Windows either.  Summarized:

if DISPLAY set (though it may be set but no X is available, at least  
on OSX)
   test gui dependency - python for wx, wish for tcltk
   if it fails
     warn that *wish* doesn't work (oops)
else
   no gui possible
   if a gui is set
     warn that *X* is not available, and there a gui is not possible  
(oops again)

Instead of testing the gui dependency first, maybe this should test  
the gui setting first:

case GRASS_GUI:
   tcltk, etc)
     test X availability
     or better, ignore DISPLAY and test only wish - if it works, X is  
implied, or whatever graphical base needed (this would take care of  
native tcltk implementations, like Aqua or Windows, not that they  
work well)
   wx)
     test python availability (X implied if needed - as long as  
python works)


...just some thoughts...
