Did you see that the Mac instructions said to follow the "other *nix" instructions if you were using an older version of Mac OS X?

Those link here: https://www.haskell.org/ghc/download_ghc_7_8_4#binaries

Get rid of all that (GHC, HP, Cabal), then install GHC using the bindist for Mac OS X linked above.

This corresponds to a fresh install of the HP, ghc, and cabal I didn't before trying to install yesod.
