This tool is used to install rbenv and some plugins. It also provides scripts to install required software to be able to compile Ruby.

Installed plugins are rbenv-vars, ruby-build & rbenv-installer.

Install git and curl:

sudo apt-get -y install git-core curl

Make sure your user has sudo privileges.

Install rbenv and friends by running:

curl https://raw.github.com/fesplugas/rbenv-installer/master/bin/rbenv-installer | bash

Install Ruby 1.9.3-p194 and make it global:

rbenv install 1.9.3-p194
rbenv global 1.9.3-p194

Update rbenv and plugins provided by the installer running:

rbenv update

If you are installing rbenv in Ubuntu you'll probably need to install required packages first:

rbenv bootstrap-ubuntu-12-04
rbenv bootstrap-ubuntu-10-04

To update RubyGems and install bundler and rake:

rbenv bootstrap

Install patched ruby-build by using the following command:

rbenv patch-ruby-build

Now when you install a new Ruby it will try to download a package from a RUBY_PACKAGE_REPO. If no packages available it will compile the package as usual.

export RUBY_PACKAGE_REPO=https://www.strongspace.com/shared/lxc1jwhowa

You can always add the previous export into your .bashrc to install always from that package repo.
