[Haskell-beginners] ghc: unrecognised flags: -I

I found the issue, and I think it may point to a bug in the cabal

I had:

  -- /opt/local/include

In my ~/.cabal/config, and as far as I could tell it was prefixing the
empty list of include paths with -I. It should probably omit the empty
list entirely. I had a quick look in the cabal configuration source,
but I think I'm out of my depth where that is concerned.

Anyway, issue resolved for me :-)
