Erro na instalação do ruby-debug
andreyq@desenv-ubuntu-9:~$ sudo gem install ruby-debug [sudo] password for andreyq: Building native extensions. This could take a while... ERROR: Error installing ruby-debug: ERROR: Failed to build gem native extension. /usr/bin/ruby1.8 extconf.rb extconf.rb:1:in `require': no such file to load -- mkmf (LoadError) from extconf.rb:1 Gem files will remain installed in /var/lib/gems/1.8/gems/linecache-0.43 for inspection.

Depois de algumas pesquisas descobri que precisava ter o pacote
ruby1.8-devinstalado para satisfazer algumas dependências.
Fiz a instalação do mesmo:
sudo apt-get install ruby1.8-dev
e tentei novamente instalar o ruby-debug:
andreyq@desenv-ubuntu-9:~$ sudo gem install ruby-debug Building native extensions. This could take a while... Building native extensions. This could take a while...

Ótimo! Desta vez obtive sucesso.
O engraçado é que eu pensava que o pacote ruby1.8-dev só seria necessário se eu fosse alterar o próprio ruby.
