Erros when installing Plugin

[shaffettea]

I am running Bitnami Redmine 2.1.4. When installing the plugin, I run rake redmine:plugins:migrate RAILS_ENV=production and get the following error:
Could not find gem 'shoulda-matchers <>= 0) x86-mingw32' in the gems available on this machine. Run bundle install to install missing gems.
When I try to run the 'bundle install', I get errors trying to reach a site on the internet. I am running this app on a standalone system with no access to the internet.

This plugin need to install some additional gems. "Bundle install" and "gem install" try ti fetch it from internet repo.
You must to have internet access than you install any Redmine-plugins (if they need sone gems)
