Redmine

Sorry to post a common issue but I have been looking for days and not yet got a solution.

I am running Redmine 2.3 on Centos 6.2 I have been using it fine for weeks using webrick, but every time I try to get it to run under Apache I cannot. Here is the error I get when I try and visit it at issue.mydomain.com.

Could not find mime-types-1.25 in any of the sources (Bundler::GemNotFound)

Here is my environment output

Environment:
  Redmine version                2.3.2.stable.12119
  Ruby version                   1.9.3-p327 (2012-11-10) [x86_64-linux]
  Rails version                  3.2.13
  Environment                    production
  Database adapter               Mysql2
Redmine plugins:
  no plugin installed

and here is my virtual host entry

Listen *:3000

#LoadModule passenger_module /usr/lib64/ruby/gems/1.9.1/gems/passenger-3.0.19/ext/apache2/mod_passenger.so
#PassengerRoot /usr/lib64/ruby/gems/1.9.1/gems/passenger-3.0.19
#PassengerRuby /usr/bin/ruby

<VirtualHost *:80>
    ServerName issues.mydomain.com
    DocumentRoot /var/www/html/redmine-2.3/public/
    ErrorLog logs/redmine_error_log
    <Directory "/var/www/html/redmine-2.3/public/">
         Options Indexes ExecCGI FollowSymLinks
         Order allow,deny
         Allow from all
         AllowOverride all
         # MultiViews must be turned off.
         Options -MultiViews
      </Directory>
</VirtualHost>

If I go to issues.mydomain.com:3000, I get the default Apache page.

I have left in the commented out bits in case they will help enlighten anyone as to my problems. I don't really know anything about Ruby, nor about Passenger so am at a loss, any help would be massively appreciated!
