title: ImportError: No module named PyQt4.QtCore
body: <p>I've reïnstalled my ssh server, so I also need to reïnstall my Python packages.</p>
  
  <p>I did that, but I still get the error:</p>
  
  <pre><code>ImportError: No module named PyQt4.QtCore
  </code></pre>
  
  <p>I've already successfully installed:</p>
  
  <pre><code>sudo apt-get install libqt4-dev
  </code></pre>
  
  <p>But still it don't work, so I tried the installation <a href="http://www.riverbankcomputing.co.uk/software/pyqt/download">instruction of PyQt4</a></p>
  
  <p>So I've tried to install SIP first, but when I run "make" <a href="http://www.riverbankcomputing.co.uk/static/Docs/sip4/installation.html">(see end of this page, <em>"Building"</em>)</a></p>
  
  <p>But I get this error:</p>
  
  <pre><code>make[1]: Entering directory `/home/francis/Downloads/sip-4.12.4/sipgen'
  g++  -o sip main.o transform.o gencode.o extracts.o export.o heap.o parser.o lexer.o 
  make[1]: g++: Command not found
  make[1]: *** [sip] Error 127
  make[1]: Leaving directory `/home/francis/Downloads/sip-4.12.4/sipgen'
  make: *** [all] Error 2
  </code></pre>
  
  <p>What do I have to do? Or is there an other way to install PyQt4?</p>
  
  <p>Thanks!</p>
