Runing Ruby and Rails off of local folder without installing them first on Mac OS X?

+1 vote
323 views

Is it possible to run Ruby and Rails on Mac OS X off of a local folder (without local or system install using RVM, Homebrew, etc.)

Similar to the way one can copy/paste Java installation directory and just run off of it with no dependencies, I'd like to do the same with Ruby/Rails.

The goal is to be able to connect a USB drive to someone's Mac OS X, open terminal, and demo an application (execute "rails server" from the mounted USB drive) without having to install/compile anything.
