Installing ruby-debug19 on ruby 1.9.3-p0 on Mac OS X Lion 10.7.2 with Xcode 4.2.1

# assumes 1.9.3-p0 is already installed in RVM (1.9.2) and you are in an empty gemset

gem install rake
gem install archive-tar-minitar
gem install ruby_core_source
gem install columnize
gem install linecache19-0.5.13.gem -- --with-ruby-include="$rvm_path/src/`rvm tools strings`"
gem install ruby-debug-base19-0.11.26.gem -- --with-ruby-include="$rvm_path/src/`rvm tools strings`"
gem install ruby-debug19

Immensely useful— just re-ran the two --with-ruby-include lines after a Ruby update and everything worked à la magique.

Merci.

Good job.

Also, seems they're on gemfury now:

Manual install

gem sources -a https://gems.gemfury.com/8n1rdTK8pezvcsyVmmgJ/   # creates ~/.gemrc
gem install ruby-debug19 -- --with-ruby-include="$rvm_path/src/`rvm tools strings`" # -- --with... for RVM only

Or with a Gemfile

source ...
source 'https://gems.gemfury.com/8n1rdTK8pezvcsyVmmgJ/' # for working pre-release ruby-debug19
...
gem 'ruby-debug19', :platforms => [ :ruby_19, :mingw_19 ]

... and to keep the build flag on Bundler ( only needed when using RVM ):

bundle config build.ruby-debug-base19 --with-ruby-include="$rvm_path/src/`rvm tools strings`" # creates ~/.bundle/config
