A search on the Apple site says it is a compile option used to remove  

The first line mentions macosx-10.3 - do you have a compiler for an  
old system, or something?

And I have a fairly recent python:
$ python --version
Python 2.5.1
$ which python

Make sure to sign up (for free) as a developer at developer.apple.com  
and take down latest Xcode (mine is Version 3.1.2, though I do not  
know if it is the absolutely latest).
