symfony with WAMP on Windows 7

my Mac has a major problem with its trackpad so i have to give it away to the lab for a while and use a PC which equiped with Windoews 7. It means I have to install Symfony with WAMP. PEAR is required for this task, but it has a fault so I have to follow this post in order to be able to install it. I use sub version with 2 different usernames to sync between the development on the Mac and PC.
