No source for ruby-1.9.2-p321 provided with debugger-ruby_core_source gem

Question

I recently updated to Mavericks. Added Command Line tools for xcode. Tried "bundle update debugger", along with every other fix I found, including this rake add_source to include the appropriate header found here:http://sponsorpay.github.io/blog/2012/06/11/ruby-debugger-and-no-source-for-ruby-error/, and I still cannot push my project to heroku without errors. Any help is appreciated. Thanks in advance.

Update: Found this but not sure how to do it. "Gems such as debugger-linecache require explicit patch levels of Ruby, this is fine for development, but should not be used in production. If you have one of these Gems in production and the patch of Ruby gets upgraded your deploy will fail.

The fix is to move your dependency out of the production group of your Gemfile." Here's the error:

   Make sure that `gem install debugger -v '1.6.3'` succeeds before bundling.

I added this to my gemfile

gem 'debugger', group: [:development, :test] 

to my gem file.

Removed my gem lock file with rm Gemfile.lock. Ran bundle install, and the push succeeded.
