I have searched high and low for a solution. I have both linecache19
and ruby_core_source
installed.
Neither of these commands will work:
gem install ruby-debug19
gem install ruby-debug19 -- --with-ruby-include=/Users/benjohnson/.rvm/src/ruby-1.9.1-p378
Here is the error I keep getting:
Building native extensions. This could take a while...
ERROR: Error installing ruby-debug19:

I have had the same issue (on 1.9.1 and 1.9.2). Even trying to install 0.11.23 triggered the error. I found that it was necessary to:
Uninstall the gem (all versions for me):
gem uninstall ruby-debug-base19
Delete the 0.11.24 directory (in my case: ~/.rvm/gems/ruby-1.9.2-p0/gems/ruby-debug-base19-0.11.24/)
install 0.11.23 explicitly:
gem install ruby-debug-base19 --version=0.11.23
This is where I got most of the solution: http://rails.brentsowers.com/2010_08_01_archive.html
Additionally, if you use Bundler:
I had problems until I upgraded to latest Bundler (1.0.2 => 1.0.7) as it insisted on installing ruby-debug-base19 v 0.11.24).
In your Gemfile, make sure you've pinned the version of ruby-debug-base19:
gem "ruby-debug-base19", "0.11.23", :require => nil
