Ubuntu 12.04 Ruby on Rails Development Environment

I haven't set up an install guide for the latest ubuntu release, largely because the last set of instructions worked pretty closely with the latest and greatest Ubuntu, 12.04 Precise Pangolin, however when installing today, I found that there were enough differences in the way that I configure my setup to justify an update, so here it goes. Yes, I'm late to the party, but a quick google search didn't find anything that I felt was as complete for my requirements as my previous install guides, so here I go.

As always with my install guides, I have included here is just about everything you'll need (and then some) to get started with ruby on rails development with Ubuntu 12.04 as a platform. These are my settings and preferences, and this is certainly not the only way of doing things, so keep that in mind.

Step 1: Get the repos ready and run updates.

sudo apt-get update && sudo apt-get upgrade

# Very important! 
# For each virtualenv you have, run "pip freeze > requirements.txt" while in the activated virtualenv 
# in order to prevent loss of dependencies during the upgrade.

sudo apt-get install -y build-essential ssh git gitk

# Databases: You may not need all of these;
# none are explicit dependencies of other items in this script.
# SQLite and MySQL are pretty generally used for web development,
# and ODBC is just something we use at work.
sudo apt-get install -y sqlite
