Python development has recently moved from using Subversion to Mercurial 
(hg).  The py3k branch in the svn repository at that URL is now frozen 
in-time and not being updated.

$ svn info
Path: .
URL: http://svn.python.org/projects/python/branches/py3k
Repository Root: http://svn.python.org/projects
Repository UUID: 6015fed2-1504-0410-9fe1-9d1591cc4771
Revision: 88828
Node Kind: directory
Schedule: normal
Last Changed Author: giampaolo.rodola
Last Changed Rev: 88761
Last Changed Date: 2011-03-06 13:04:47 -0800 (Sun, 06 Mar 2011)

Information on how to access the hg repos is contained in the new Python 
Developer's Guide:

   http://docs.python.org/devguide/setup.html

If you use hg to clone a copy of the current repo, you'll see something 
more like this:

$ hg clone http://hg.python.org/cpython
$ cd cpython
$ hg log -b default
changeset:   69534:020ebe0be33e
user:        Antoine Pitrou <solipsis at pitrou.net>
date:        Sat Apr 23 17:56:06 2011 +0200
summary:     Remove unused private function

Try the build again from a clean directory using the current hg repo.  
That said, if the message appears, follow the directions about copying 
Modules/Setup.dist to Modules/Setup.  That is likely the source of your 
original build failure.

That is out-of-date as well.  All current development and maintenance 
branches (2.7, 3.1, 3.2, default(=py3k)) are now maintained in the hg 
repo as described in the developer's guide.
