title: How to run pyside_postinstall.py on virtualenv copy of PySide?
body: <p>I get the following error when attempting to run a virtualenv ipython on the qt gui:</p>
  
  <pre><code>ImportError: libpyside-python2.7.so.1.2: cannot open shared object file: No such file or directory
  </code></pre>
  
  <p>To 'install' PySide on my virtualenv I just copied over system built PySide from <code>/usr/local/lib/python2.7/dist-packages</code> to the virtual environment's <code>site-packages</code>. I understand the post installation script does the dynamic linking. This obviously works for the system installed PySide package but how do I run post installation similarly for the virtualenv copied libs?</p>
