I installed openproject yesterday on a Ubuntu server 12.04 virtual server, following the guide at https://www.openproject.org/projects/openproject/wiki/Installation_Ubuntu - and managed to get it working.

I am trying to install some of the plugins, and have added the information to the Gemfile.plugins file as detailed at https://www.openproject.org/projects/openproject/wiki/OpenProject_Plug-Ins
However, when I run ‘bundle install’ it mentioned nothing about fetching any files, etc. It immediately says
using rake 10.1.0
using i18n 0.6.8
etc
etc.
It then says ‘your bundle is complete!’ It never mentions downloading & installing the plugins, and when I start up the rails server and login, absolutely nothing has changed.

I am somewhat new to using the Linux command-line, and totally new to Ruby/Openproject etc, so please bear with me.
Am I doing something wrong, or am I missing something? Any help would be much appreciated.
Thanks
