 The Building/Preparation/MacOSX page suggests using Darin Morrison's
 brewtap to install ghc using Homebrew:

     3. Use one of Fink, MacPorts or Brew. If using brew, we strongly
 recommend using Darin's ​brewtap for ghc

 Darin's brewtap, however, is deprecated:

     https://github.com/darinmorrison/homebrew-haskell

 For the most part, it seems that the default homebrew install works
 correctly, but `./configure` fails because Happy is not installed.

 We should either (1) remove the recommendation to use Homebrew or (2)
 explain how to install all of the necessary components to build GHC.  (I
 couldn't figure out how to install Happy using Homebrew's cabal-install
 formula, so I used the GHC Platform instead.)
