title: PyQt4 can't import Qsci
body: <p>I'm installing PyQt4 on an old Linux system (CentOS 4.4) that can't be upgraded for hardware compatibility reasons. I've got Python 2.6, QT4 and SIP installed, and the installation of PyQt4 didn't give me any errors.</p>
  
  <p>When I run Python, this happens:</p>
  
  <pre><code>Python 2.6.2 (r262:71600, May 11 2011, 14:18:37) 
  [GCC 3.4.6 20060404 (Red Hat 3.4.6-3)] on linux2
  Type "help", "copyright", "credits" or "license" for more information.
  &gt;&gt;&gt; import PyQt4
  &gt;&gt;&gt; import PyQt4.Qsci
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  ImportError: No module named Qsci
  </code></pre>
  
  <p>I looked around, and found <code>/usr/local/lib/python2.6/site-packages/PyQt4/uic/widget-plugins/qscintilla.py</code>, which is almost empty of non-comment stuff:</p>
  
  <pre><code>pluginType = MODULE
  
  def moduleInformation():
      return "PyQt4.Qsci", ("QsciScintilla", )
  </code></pre>
  
  <p>Any ideas?</p>
