These notes were for a job I am no longer at and are very dated. Please go to the imagemagick website for updated instructions.
The version of ImageMagick that is installed when you run apt-get install imagemagick on Ubuntu 14.04 is older than I would like.

The sendmail package, which comes preinstalled with many distros, is often simply too much for a simple server that should not receive emails but rather deliver them. The sSMTP package is a lightweight replacement that does not set up regular cronjobs and only reacts if a subsystem actually wants to send a mail.
apt-get purge --yes sendmail*

Use my fork of the Wiring-Pi Python library which checks out the WiringOP fork of the WiringPi library as a submodule to build everything. yes that's a little confusing
The WiringPI library is the original C library that RaspGPIO is somewhat based on. WiringPi was built to replicate arduino GPIO functions
In Raspberry Pi Land there are 2 normal python paths for GPIO. One is Raspi.GPIO and the other is WiringPI
