brew install mighty-gerbils/gerbil/

Or brew tap mighty-gerbils/gerbil and then brew install .

** Build the HEAD of Master

Sometimes, like for testing pre-release, we want to build and test the lastest commit to the =master= branch.

#+begin_src sh brew install mighty-gerbils/gerbil/gerbil-scheme #+end_src

brew help, man brew or check Homebrew's documentation.
