Compile failed MacOS

[andrewnc]

Hello! I'm trying to install and compilation fails, I'm too much of a Haskell novice to know where to look.

Burlesque/Eval.hs:27:1: error:
    Could not find module ‘Data.ByteString.UTF8’
    Perhaps you meant
      Data.ByteString.Char8 (from bytestring-0.10.8.2)
      Data.ByteString.Lazy (from bytestring-0.10.8.2)
      Data.ByteString (from bytestring-0.10.8.2)
    Use -v to see a list of the files searched for.
   |
27 | import qualified Data.ByteString.UTF8 as B8
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I'm using version 8.6.3 of ghc.

You're lacking the package that provides Data.ByteString.UTF8 which you'll need to install through cabal. If you use a plain haskell installation it's very likely that you'll also have to install a lot more packages.
