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.
