6 steps to set up a rails development environment on OS X:

install Apple Command Line Tools
install homebrew[1]: /usr/bin/ruby -e "$(/usr/bin/curl -fksSL https://raw.github.com/mxcl/homebrew/master/Library/Contributions/install_homebrew.rb)"
install rvm: bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
install ruby rvm install 1.9.3
install rails

Patched ruby 1.9.3-p125 for 30% faster rails boot

What is?

This script installs a patched version of ruby 1.9.3-p125 with patches to make ruby-debug work again (#47) and boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84). It also includes the new backported GC from ruby-trunk.

Huge thanks to funny-falcon for the performance patches.
