title: "unrecognized .svn/entries format" using buildout
body: <p>Since upgrading to subversion 1.7 I get "unrecognized .svn/entries format" when running buildout.  I notice there is an unresolved bug reports for both distribute and setuptools for this error and it also seems that you can use <a href="http://pypi.python.org/pypi/setuptools_subversion" rel="nofollow">setuptools_subversion</a> to resolve the issue.</p>
  
  <p>What I can't find out how to do is install setuptools_subversion so that buildout picks it up.  Please can  someone help?</p>
  
  <p>I've tried </p>
  
  <ul>
  <li>downloading it and running python setup.py install</li>
  <li>adding it to the eggs list of the [buildout] part of my buildout configuration</li>
  </ul>
