You could try the '--local', which should prefer already installed gems.

I am not aware of any better way how to do it. But may be somebody from 
Aeolus or Katello could provide more information, since they are using 
similar workflow, i.e. they are developing with RPM gems.

Once you have everything installed, the 'bundle install --local' should 
update your Gemfile.lock just fine.

Actually, is there reason to use Gemfile and Bundler at all? I would say 
that the Rails application will work without it just fine.
