To install this formula:
brew install https://gist.github.com/raw/4440291/sfml.rb --HEAD --build-examples

@juniorz Now that SFML 2.0 has been released would it be possible for you to submit this to the main Homebrew repository? Thanks.

Trying to build this results in:

  % brew install https://gist.github.com/raw/4440291/sfml.rb --HEAD --build-examples                            !6496
