Official procedure to build from source bundled with GHC source tarball?

[Compl Yue]

Hello folks,

I'm trying to install cabal after built ghc 8.8.2 on smartos, seems the 
src bundled within ghc src tarball not working:

I wonder what's the official way to do it?

btw, I don't know why I can not send msg to the freenode #cabal channel:

||Thanks with best regards,
