No source for ruby-1.9.3-p374 provided with debugger-ruby_core_source gem

After updating Ruby to 1.9.3-374 debugger stopped working:

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

        /home/mencio/.rvm/rubies/ruby-1.9.3-p374/bin/ruby extconf.rb

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:

Gem files will remain installed in /path/gems/debugger-linecache-1.1.2 for inspection.
Results logged to /path/gems/debugger-linecache-1.1.2/ext/trace_nums/gem_make.out
An error occurred while installing debugger-linecache (1.1.2), and Bundler cannot continue.
Make sure that `gem install debugger-linecache -v '1.1.2'` succeeds before bundling.

How can we fix this?

gem install debugger-linecache -v '1.1.2' -- --with-ruby-include=\$rvm_path/src/ruby-1.9.3-p374

And that's all!

  6. For RBENV

    If you don’t have sources, install with ‘–keep’ option
    rbenv install –keep 2.0.0-p353

  7. Cheers mate, y’re a legend. Still helpful, works with 1.9.2-p136
