Thank you for setuptools!  We are using it in the Allmydata-Tahoe  
project [1].  We've patched ez_setup.py so that installation can  
proceed if an older version of setuptools is already present, as long  
as that version is not too old.  This allows ez_setup.py to work  
seamlessly in more situations.  Please apply.

The patch is in-lined and attached.

   * change the 'ez_setup.py' script to have distinct desired &  
minimum required versions of setuptools

   Note that this preserves backwards compatibility -- if no minimum  
version is
   specified then the default version is used as the minimum version,  
which is
   identical to the behavior before this patch.

   This patch is originally due to Rob Kinninmont.
