Nodejs on Ubuntu 12.04

Obtaining a recent version of Node or installing on older Ubuntu and other apt-based distributions may require a few extra steps. Example install:
sudo apt-get update
sudo apt-get install -y python-software-properties python g++ make
sudo add-apt-repository -y ppa:chris-lea/node.js
sudo apt-get update

sudo apt-get install nodejs

Check the node version:

node --version
