Debug Not Working After Upgrade To Ruby 1.9.3 And Rails 3.2.2

问题

I have upgraded my app to use Ruby 1.9.3p0 and Rails 3.2.2. To get bundler working I changed this:

gem 'ruby-debug'

to this:

gem 'ruby-debug19'

Now rails server gives:

Could not find archive-tar-minitar-0.5.2 in any of the sources 
Run `bundle install` to install missing gems.

Running bundle install does not help. The error goes away when I remove ruby-debug19 gem from my Gemfile, but then debugging does away too.

I also tried changing the Gemfile to:

gem 'ruby-debug19', :require => 'ruby-debug'

No help. I'm kinda new to Rails, so maybe it's something obvious.
