Issue with Advance Git Intergartion with Redmine-2.2.0 using Grack

I am trying to do the advance integration of Git with Redmine and looked into the thread discussed the similar problem link text

I am using Native Installer Redmine 2.2.0 for Linux and followed the steps from the Bitnami wiki.

After completing step-4 if I try to access Redmine Page I get the passenger error (though git clone works)

Passenger error #2 An error occurred while trying to access '/opt/redmine-2.2.0-0/apache2/htdocs/grack/public/redmine': Cannot resolve possible symlink '/opt/redmine-2.2.0-0/apache2/htdocs/grack/public/redmine': No such file or directory (2)

I have checked the passenger path is correct in installdir/apache2/conf/httpd.conf

LoadModule passenger_module /opt/redmine-2.2.0-0/ruby/lib/ruby/gems/1.9.1/gems/passenger-3.9.1.beta/libout/apache2/mod_passenger.so
PassengerRoot /opt/redmine-2.2.0-0/ruby/lib/ruby/gems/1.9.1/gems/passenger-3.9.1.beta
PassengerRuby /opt/redmine-2.2.0-0/ruby/bin/ruby

<VirtualHost *:8080>
    DocumentRoot "/opt/redmine-2.2.0-0/apache2/htdocs/grack/public"
    <Directory "/opt/redmine-2.2.0-0/apache2/htdocs/grack/public">
        Options None
        AllowOverride None
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

I also noticed when starting (or stopping) the server there is warning saying passenger_module is already loaded.

$ sudo ./ctlscript.sh start
