title: import pygtk works but not import gtk
body: <p>I am configuring pygtk in my centos 5.4 machine. But I am facing few issues.</p>
  
  <p>I want pygtk to be configured to Python 2.7(The default python version is Python 2.4 in centos 5)</p>
  
  <p>So I installed Python 2.7 with different --prefix to my local space and then installed pygobject2.28 and then pygtk2.24 with the --prefix="where python 2.7 installed".</p>
  
  <p>But when I run python2.7 interpreter I am able to import pygtk but, when I try to import gtk it says "no module named gtk."</p>
  
  <p>I have configured PYTHONPATH and PYTHON environment variables to python2.7/lib/site-packages and python2.7 respectively.</p>
  
  <p>My questions: </p>
  
  <ol>
  <li>if pygtk is a wrapper for gtk then why am not able to import gtk, when I am able to import pygtk.</li>
  <li>Where does python(or pygtk) pick the gtk from?</li>
  <li>And how can I solve the above problem!?</li>
  </ol>
  
  <p>I tried google and other stack overflow questions. But none of them answered the above quesions.</p>
