curl -OL http://rubyforge.org/frs/download.php/75414/linecache19-0.5.13.gem
curl -OL http://rubyforge.org/frs/download.php/75415/ruby-debug-base19-0.11.26.gem

gem install linecache19-0.5.13.gem ruby-debug-base19-0.11.26.gem -- --with-ruby-include=$rvm_path/src/ruby-1.9.3-p0/

rm linecache19-0.5.13.gem ruby-debug-base19-0.11.26.gem

echo "Done."

Or you can do only this:

gem install linecache19 ruby-debug-base19 -- --with-ruby-include=$rvm_path/src/ruby-1.9.3-p0/

Without linecache19-0.5.13 and ruby-debug-base19-0.11.26 you can install. When you require 'ruby-debug':

The one-liner you presented in the commented code did it for me! Finally I can use rdebug, thanks! I use Ubuntu 11.10 together with rvm.

good!
