Setting up and installing rbenv, ruby-build, rubies, rbenv-gemset, and bundler

This guide enables you to install (ruby-build) and use (rbenv) multiple versions of ruby, isolate project gems (gemsets and/or bundler), and automatically use appropriate combinations of rubies and gems.

TL;DR Demo

# Ensure system is in ship-shape.

aptitude install git zsh libssl-dev zlib1g-dev libreadline-dev libyaml-dev

# Update, upgrade and install development tools:
sudo apt-get update
sudo apt-get -y upgrade
sudo apt-get -y install build-essential git-core libssl-dev libsqlite3-dev curl nodejs nginx

# Install rbenv
git clone git://github.com/sstephenson/rbenv.git ~/.rbenv

# Add rbenv to the path:
echo 'export RBENV_ROOT=~/.rbenv' >> ~/.bash_profile
