title: Why does easy install want access to my rootfs for a "develop" install?
body: <p>I'm looking at a python application server and I wanted to play around with the code. I'm lead to believe passing "develop" to setup.py should leave everything in place without installing anything. However when running so it is attempting to creating directories in my rootfs.</p>
  
  <pre><code>./setup.py develop
  </code></pre>
  
  <p>Gives:</p>
  
  <pre><code>running develop
  Checking .pth file support in /usr/local/lib/python2.7/dist-packages/
  error: can't create or remove files in install directory
  </code></pre>
  
  <p>I thought this might be something to do with package checking but surely attempting to write stuff into the rootfs is wrong?</p>
