I want to do it but as it is a clark connect server, there is still no
latest rpm available and as it is a development server I have made
myself slower to upgrade it manually from individual .rpm. I like to
solve the present hook problem first and then I'll go for up-gradation
by collecting .rpm from net.

yes, true. I actually created the /var/www/html/POSTCOMMIT and then
did a checkout inside it. after that I made the directory as apache:apache
