What's the full traceback?  I can't tell from just those two lines 
what's actually going on.

Offhand, my guess is that the script location you're installing the 
new version to is later on your PATH than the old version.  It looks 
like your PYTHONPATH is correct, but that the 'easy_install' 
executable wasn't overwritten when you installed the newer version -- 
i.e., the new version installed its script to a different location 
that's either not on your PATH or is after the location where the old 
easy_install script is.

So, I would probably do a 'which easy_install' to find out which one 
you're running (I'm assuming OS X includes a 'which' command, which 
it may not) and then run 'ez_setup -U --script-dir=/whatever 
setuptools' where '/whatever' is the directory where your current 
'easy_install' executable is.
