Go to bugs.gentoo.org, search for ALL dev-pyton/setuptools, and check the 
bugs from say 280000 on.  In this case, the bottom four bugs as of this 
writing are all duplicates on this, with ....

http://bugs.gentoo.org/show_bug.cgi?id=292095

... being the one the other three are duplicates off of.  Doing that gets 
you about the same information you're going to get by posting here, only 
you don't have to wait for a reply to get it.

In this case, the bug should be already fixed.  Resync and try again.  If 
it does happen to still be an issue after a sync and retry, then you may 
have another bug to worry about.  File it and mention that you DID sync 
and try again, and either your mirror is lagging (bug in the mirror 
infrastructure) or there's another ebuild bug to worry about.
