These instructions work for the Raspberry Pi running Raspbian (hard float) and create a hardware optimized version of NodeJS for the Raspberry PI, (and include a working install and NPM!!!):

1. Install Raspbian - http://www.raspberrypi.org/downloads

2. Install the necessary dependecies:

sudo apt-get install git-core build-essential

(If you just installed git then you need to administer your git identity first, else adding the patches below will fail!!!)

What the Hell? -- A Journey Through the Nine Circles of Python Packing
