title: Easy_install's --prefix option doesn't change where it tries to install my package
body: <p>I want to install Sphinx 1.1.3 for python 2.6. However, I don't have sudo rights. So instead of installing it in the default place, I want to set a different location, using --prefix. Doing the following:</p>
  
  <pre><code>-bash-3.2$ easy_install Sphinx-1.1.3-py2.6.egg --prefix=/homes/ndeklein/python2.6/site-packages/
  </code></pre>
  
  <p>gives me:</p>
  
  <pre><code>error: can't create or remove files in install directory
  
  The following error occurred while trying to add or remove files in the
  installation directory:
  
  [Errno 13] Permission denied: '/usr/lib/python2.4/site-packages/test-easy-install-18534.write-test'
  
  The installation directory you specified (via --install-dir, --prefix, or
  the distutils default setting) was:
  
  /usr/lib/python2.4/site-packages/
  </code></pre>
  
  <p>Am I typing something wrong with the prefix? Also, what I could use instead (which I've used with other packages): </p>
  
  <pre><code>python setup.py install --home=/homes/ndeklein/python2.6/site-packages/
  </code></pre>
  
  <p>but I can't find the setup.py script. I'm guessing that EGGs don't have a setup.py script, is that true?</p>
