sane rubygems on Ubuntu Lucid

gistfile1.sh

The version of rubygems is too old in the Lucid repositories so I make use of a thirdparty PPA. 
This PPA is from Mackenzie Morgan - a Ubuntu Developer - https://launchpad.net/~maco.m/+archive/ruby

1) add Mackenzie's PPA

    sudo apt-get install python-software-properties
    sudo add-apt-repository ppa:maco.m/ruby

2) let apt see the new repositories

    sudo apt-get update

3) install newer rubygem

    sudo apt-get install rubygems

4) install bundler

    sudo gem install bundler

5) add _/var/lib/gems/1.8/bin_ to your $PATH
