Installing Rubygems

1) Because Debian does not automatically include all the standard Ruby libraries in the basic Ruby package, we need to install essential libs:

$ sudo apt-get install libyaml-ruby libzlib-ruby

2) Download rubygems from rubyforge then:

	$ tar xvfz rubygems-n.n.n.tgz
	$ cd rubygems-n.n.n
	$ sudo ruby setup.rb

4) And then finally:

	$ echo 'export RUBYOPT=rubygems' >> ~/.bashrc
