title: ubuntu9.10 : how to use python's lib-dynload and site-packages directories?
body: <p>In ubuntu 9.10, in usr/lib/ there are the directories python2.4, python2.5, python2.6 and python3.0 </p>
  
  <p>Only python 2.6 is actually working.<br>
  python2.4 has only a lib-dynload directory,<br>
  python2.5 has only lib-dynload and site-packages,<br>
  python3.0 has only a dist-packages directory.  </p>
  
  <p>Now i'm wondering what is the idea behind this? 
  Because when i install python2.5 with ./configure, make, make install | altinstall
  this goes into usr/local/lib and not usr/lib/ so why were these directories added tu ubuntu, how am i supposed to install python to use them?</p>
