Apple recently pushed a breaking change to Xcode (Xcode 5.1) that, if you're using the version of Ruby that comes with your computer, will make it impossible to install any Ruby gems that need native extensions. While Breakpoint doesn't need any, Compass requires the JSON gem, which does.
There is a Compass Issue to track progress on the removal of direct dependence on the JSON
gem and instead require multi_json
exclusively.
In a Breakpoint Issue identical to this problem, I describe in detail what's going on and provide options on how to solve the issue.
