Bitnami Redmine 2.1.2-1 build and advanced git integration

hi, I've just installed your Redmine VMWare build and thanks for your work. It works great and we're very eager to begin using it. I've just a little problem with the advanced git integration part. I've tried to use the guide in the documentation, but I can get git to work using the rackup on port 8080. But as soon i try to set it up to use port 80 in apache2 it fails. Some of the steps described in the doc is already there?!? And when I write the virtualhost part I cant browse to MyIP/redmine. In apache2 error_log i get this:

[ pid=1088 thr=139716474271488 file=ext/apache2/Hooks.cpp:148 time=2012-11-21 21:11:38.956 ]: A filesystem exception occured.
  Message: Cannot resolve possible symlink '/opt/bitnami/apache2/htdocs/grack/public/redmine': No such file or directory (2)
  Backtrace:
     in 'int Hooks::handleRequest(request_rec*)' (Hooks.cpp:564)

and if I don't write in the virtualhost part I get this:

[Wed Nov 21 15:26:17 2012] [error] [client 10.59.16.179] File does not exist: /opt/bitnami/apache2/htdocs/myRepo

My repo is in /opt/bitnami/projects/myRepo

does any of you have an idea what it can be??

BR, Thomas
