Using Apple's Python 2.3 on 10.3.4, mac_ver() fails for me:

 >>> import platform
 >>> print platform.mac_ver()
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File  
"/System/Library/Frameworks/Python.framework/Versions/2.3/lib/ 
python2.3/platform.py", line 563, in mac_ver
     sysv,sysu,sysa = _mac_ver_lookup(('sysv','sysu','sysa'))
   File  
"/System/Library/Frameworks/Python.framework/Versions/2.3/lib/ 
python2.3/platform.py", line 532, in _mac_ver_lookup
     append(gestalt(selector))
MacOS.Error: (-5551, 'undefined selector was passed to Gestalt')

My machine doesn't like to do gestalt.gestalt('sysu') (and raises the  
wrong exception for platform.py's  _mac_ver_lookup()?).
