Mountain Lion and You
Raw
mountain_lion.md
  • stay calm
  • do not approach, and give it a way to escape
  • do not run, as it may encourage it to chase you
  • do not crouch or bend over, as you may look more like a 4-legged prey animal
  • do all you can to appear larger. raise your arms and open your jacket.

Installing

  • install Mountain Lion
  • Upgrade XCode
  • Upgrade the command-line tools using the XCode preferences. If you get a cryptic error about not having access, get the command line tools directly from apple's developer site
  • download and install xquartz from their site
  • brew update
  • brew tap homebrew/dupes
  • brew install apple-gcc42
  • rvm get head
  • rvm reload
  • rvm reinstall all your rubies.

And you're good to go. If you're still concerned about ruby gems, you can always run gem pristine --all in any of your gemsets.
