My understanding is that if there is a system Python, you shouldn't  
change it.  Ever.

System Python's are for other components of the system; you can use  
them, but shouldn't modify them.  Including installing or updating  
packages in the site-packages directory.

At Zope Corporation, we use a clean Python for all development and  
deployments.  Nothing gets installed into the site-packages, because  
different applications want different packages (or different  
versions), and we want to deploy with what we test with.

Indeed.  I've never had to do anything to maintain the system Python  
on Mac OS X.  It's there, Mac OS X does what it will with it, and I  
use my private (and squeaky clean!) Python installations.
