title: How to get setuptools to use a relative path in easy-install.pth when doing "setup.py develop"
body: <p>I'm installing a python egg using setuptools with the "python setup.py develop" command.  It's important that all install paths be relative.  I see that I can do:</p>
  
  <pre><code>python setup.py develop --egg-path ../../../../my_directory
  </code></pre>
  
  <p>and the .egg-link file uses that relative path.  However, the path added to easy-install.pth still is an absolute path.  How do I make the path in the easy-install.pth file a relative path?</p>
