title: PyCharm 3.0 fails to find PyQt5
body: <p>I've got Python 3.3.2 installed (both x86 and x64 versions) and PyQt5.1 installed on top of them.</p>
  <p>Recently I installed PyCharm 3.0 Community Edition and configured to work with these Python interpreters. The problem is that PyQt5 is not shown in the list of installed packages and documentation is not working (both <kbd>Ctrl</kbd>+<kbd>Space</kbd> to autocomplete and <kbd>Ctrl</kbd>+<kbd>Q</kbd> for docs).</p>
  <p>When PyCharm is quering skeleton generation it seems to process PyQt but to no use. When I try to install PyQt using packages system inside PyCharm, I get following error:</p>
  <pre><code>C:\Program Files (x86)\PyCharm3.0\helpers\packaging_tool.py run on 10/06/13 13:58:52

  <p>Error:</p>
  <pre><code>pip.exceptions.DistributionNotFound: No distributions at all found for PyQt5
  </code></pre>
  <p>But it seems that this is unrelated problem.</p>
  <p>PyQt5 is installed with binary installer. System is Win 7 x64.</p>
  <p>Update:
  I've found log from previous index invalidating I tried to make things work. The log contains no errors or warnings concerning PyQt. Specifically it reads as follows:</p>
  <pre><code>INFO - .skeletons.PySkeletonRefresher - Home path is C:\Program Files (x86)\PyCharm3.0 
  INFO - .skeletons.PySkeletonRefresher - Pregenerated skeletons root is C:\Program Files (x86)\PyCharm3.0\skeletons

  <p>Maybe some problem lies in packaging tool:</p>
  <pre><code>INFO - packaging.PyPackageManagerImpl - Running packaging tool: C:/Python/332_x64/python.exe C:\Program Files (x86)\PyCharm3.0\helpers\packaging_tool.py list
  </code></pre>
  <p>But there are no errors reported still.</p>
