The python installed under /System/Library is installed and updated by 
Apple as a part of OSX.  The general rule is the file system space under 
/System is owned by Apple and OSX;  third-parties, including users and 
ISVs, should not remove or rename any existing files there.  That's why 
the MacPython 2.5.x distribution installs in /Library, the MacPorts 
version in /opt/local, and the Fink version in /sw.  The good news is 
that they all co-exist with each other and with the Apple-installed 
python.  The only "trick" is to make sure you're invoking the expected 
python.  From a shell (terminal command line), one way to do that is by 
manipulating shell environment variables (e.g. PATH) to ensure the 
desired python is found first.  The installer for MacPython 2.5.x (from 
python.org) has a package to do that for you.  Another way to get the 
desired Python is to explicitly reference the python you want (see 
followup reply).
