Hi all,
Don't bother uninstalling. It'll just come back in updates.mapple leaves /usr/local completely alone, so edit /etc/paths to have /usr/local/bin first. Then, install Xcode via the AppStore so you can compile ruby and gems with c extensions. Then install Mac homebrew and use that to install ruby 1.9. Rvm is nice in certain contexts but really isn't necessary and overly complicates things.

Options is not an array, it's a hash. but in any case it's never going
to be equal to "add". It will contain an element or a key "add".
