ruby-debug with Ruby 1.9.3?

Maybe not the definitive answer to this question, but I was lead here by a chain of closed duplicates.

For me the problem was that I run a project in both ruby 1.8 and ruby 1.9, and my Gemfile needed this change:

gem 'debugger', :require => 'ruby-debug', :platforms => :mri_19
gem 'ruby-debug', :platforms => :mri_18

Now it works for both rubies.
