It was an interesting day since I successfully installed subversion and trac on my home computer in windows. Wow it was much simple than I expected. Be careful subversion does not have binding for python 2.4.x I wasted couple of hours on that. So just follow the in instruction as it is in this page.

Hi Imthiaz,
