If you're using ruby1.9.2 try:

group :development, :test do
  gem 'ruby-debug19', :require => "ruby-debug"
end

in your Gemfile.


I'd imply you should update to Rails 3.0.1 because of a security-update for nested attributes (if you use 'em).

You need to install ruby-debug to run the server in debugging mode. With
gems, use 'gem install ruby-debug'
Exiting

tiberius:project Jonathan$ gem list

*** LOCAL GEMS ***
...
ruby-debug (0.10.4)
ruby-debug-base (0.10.4)
...

The gem also appears to run okay:

tiberius:project Jonathan$ irb
require 'ruby-debug'
=>  true

Any idea why it's not working?
