Hi,
I tried to get GHC working from the repo in Mac OS X following the instructions in https://gitlab.haskell.org/ghc/ghc/wikis/building/preparation/mac-osx. At first I got the "error __GNU_MP_VERSION not defined" problem, for which the guide recommends to prepend "CC=clang"  to "./configure" , which I did. But even then, I also had to install "gmp" using "brew install gmp".
1. Is it right that I need to install gmp using brew or did I miss some previous step?
2. If (1) is affirmative, how can I help update the docs for building in Mac OS X?


I've encountered this problem. In my case it turned out that I had a rogue `cc` executable in my path. See https://gitlab.haskell.org/ghc/ghc/issues/16904 for details.
