How to enter rails console on production via capistrano?

I want to enter the rails console on production server from my local machine via capistrano. I found some gists, e.g. https://gist.github.com/813291 and when I enter console via

cap production console 

I get the following result

192-168-0-100:foldername username $ cap console RAILS_ENV=production
  * executing `console'
  * executing "cd /var/www/myapp/current && rails console production"
    servers: ["www.example.de"]
    [www.example.de] executing command
    [www.example.de] rvm_path=$HOME/.rvm/ $HOME/.rvm/bin/rvm-shell '1.9.3' -c 'cd /var/www/myapp/current && rails console production'
/var/www/myapp/releases/20120305102218/app/controllers/users_controller.rb:3: warning: already initialized constant VERIFY_PEER
Loading production environment (Rails 3.2.1)
Switch to inspect mode.

and thats it... Now I can enter some text, but nothing happens...

Has anybody an idea how to get that work or another solution for my problem?
