Redmine

Hi, just today I tried to install the new version of the redmine (2.3.1) on the apache and on the debian

I installed everything which is needed:
ruby 1.9.3
rails 3.2.13
rubygems 1.8

The tutorial which I used is on the:
http://www.cynapse.com/community/home/cyn.in-developers/install-redmine-on-debian

Everything went fine, just changed paths to the files and didnt get too many errors :). Now when i try to visit site to see if it works i get this error:
