# sys.executable is a /usr/local/bin/python2.3 symlink
 >>> import os, sys
 >>> 'Python.framework' in os.path.realpath(sys.executable)
True
 >>> 'Python.framework' in sys.executable
False

They'd have to be pretty crazy if they renamed the framework to 
something else.  Does site.py get loaded if the interpreter is embedded 
in another app?  If so, that potentially cause the os.path to miss...  
but you might not care if you're embedding python(?).
