Note that with Mac OS X, it comes pre-packaged with Ruby and Rubygems, however, Middleman has dependencies that needs to be compiled during installation and on OSX that requires Xcode. You can install the latest version of Xcode via the Mac App Store. However, If you have a free Apple Developer account, you can also just install Command Line Tools for Xcode from the developer’s downloads page.
