He instalado Ruby on Rails usando rvm. Estoy usando Ruby 2.2.0 y Rails 4.2.0. Intenté ejecutar la instalación del paquete en un proyecto anterior que desarrollé en una PC anterior, pero aparece:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in /home/florin/.rvm/gems/ruby-2.2.3/gems/debugger-1.6.8 for inspection.
Results logged to /home/florin/.rvm/gems/ruby-2.2.3/extensions/x86_64-linux/2.2.0/debugger-1.6.8/gem_make.out
An error occurred while installing debugger (1.6.8), and Bundler cannot
continue.
Make sure that `gem install debugger -v '1.6.8'` succeeds before bundling.
Leyendo Internet intenté instalar todas las cosas de desarrollo como: sudo apt-get install libpq-dev
sudo apt-get install libmysqlclient-dev
sudo apt-get install libpq-dev
sudo apt-get install libsqlite3-dev
sudo apt-get install libev-dev
pero no funcionó.

Me pasó lo mismo cuando pasé de ruby-1.9.3-p385 a ruby-2.2.3.
Parece que cuando generas el proyecto, Rails usará las gemas apropiadas para la versión Ruby, que no se garantiza que funcionen para otras versiones de Ruby.
En este caso, el depurador no soporta Ruby después de 2.1.1, y puedes hacer que esto funcione reemplazando:
gem 'debugger'
con:
gem 'byebug'
en tu Gemfile.
