Okay, I tested this patch on Mac OS X and it worked.  First I  
installed setuptools v0.6c3, then I tried to execute allmydata.org 's  
"setup.py install".  I got the error message saying that it couldn't  
install a newer version of setuptools (v0.6c7) when an older version  
was already loaded.  Then I applied my patch to ez_setup.py and tried  
again.  This time it installed v0.6c7.
