[Haskell-cafe] Error trying to build haskell-dbus on FreeBSD

I am trying to build haskell-dbus on FreeBSD 12.1. I have tried with stack 2.1.3.1, and with cabal 2.4.0.0. I am seeing this error: Not in scope: type constructor or class ‘HsType’ Full error: https://gist.github.com/codedmart/2b04438566ed8e985d909db7d426649c HsType is part of ghc unless I am missing something. I am new to using FreeBSD as I usually use Linux. This package builds fine for me on Linux. Thanks -- Brandon Martin
