This appears to be another instance of being bitten by the Apple Leopard 
Python sys.path misfeature.  In short, the Apple-supplied Python for 
10.5 ships with the older version of setuptools and, because of the 
order of directories on its sys.path, the older version is always found 
first.

Jack suggests a workaround in this thread:

So you could try putting a .pth hack for the newer setuptools into one 
of the directories on sys.path as he suggests.
