title: Ubuntu 14.04 - Qt version choosing
body: <p>I mistakenly updated my qt version from 4.8.5 to 4.8.6. This happened as a result of python anaconda installation.</p>
  
  <p>However I am working on a project that needs qt 4.8.5. </p>
  
  <p>Running <code>qmake -v</code> shows:</p>
  
  <pre><code>$ qmake -v
  QMake version 2.01a
  Using Qt version 4.8.6 in home/&lt;username&gt;/anaconda/lib
  </code></pre>
  
  <p>How do I switch to my previous qt version (installed in the default directory, i.e. /usr/... )?</p>
  
  <p><code>qtchooser</code> lists the following options:</p>
  
  <pre><code>$ qtchooser -list-versions
  4
  5
  default
  qt4-i386-linux-gnu
  qt4-x86_64-linux-gnu
  qt4
  qt5-x86_64-linux-gnu
  qt5
  </code></pre>
  
  <p>But trying <code>export QT_SELECT</code> with every option didn't change the message:</p>
  
  <pre><code>Using Qt version 4.8.6 in home/&lt;username&gt;/anaconda/lib
  </code></pre>
  
  <p>I will greatly appreciate your help.</p>
