Here is a script that I wrote and have been using, should work on most Linux's and OSX to bootstrap a Rails Development environment. Also ensures that git is installed. You can run it with one command (after reading it's contents of course) as follows:

curl -O https://github.com/wayneeseguin/rvm/blob/master/contrib/boot... && source bootstrap_rails_environment

This automates installing the prerequisites across many Linux package management types and then bootstraps a Rails development environment using RVM.

A few questions:

-Why Ruby 1.8.7 and not 1.9.2?

-I've installed 1.8.7, 1.9.2 & 1.9.2-head via RVM without having libyaml-dev or libffi-dev installed (I see they're listed in `rvm notes`). Any idea what's up here?

Thanks!

Read the script, it's adjustable. Download, change your version and run. They are listed as they help 'cover all bases' as they are used by some gems that people might need.
