title: Unable to use Auto Config for PyDev interpreter setup
body: <p>In setting up PyDev with my Python Interpreter, I select "Auto Config" to bring up a list of directories.  Then press OK, and get an error message:</p>
  
  <pre><code>Error: Python stdlib not found or stdlib found without .py files.
  </code></pre>
  
  <p>Apparently, it is looking for files such as threading.py and traceback.py (not just their executables).</p>
  
  <p>And yet, I am able to find both of these files in <code>/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7</code></p>
  
  <p>One of the folders in "Auto Config" folder list is precisely that folder, so I am really lost as to what the problem is.  I'm using Mac OS X 10.7.3 and Python 2.7.3 from python.org.</p>
