Based on this issue it sounds like I need to solve the general problem of pointing hint to a ghc package db... which may or may not exist... further that package db needs to at least have all of the packages that we depend on in it... hrrmmm.

can use stack exec --no-ghc-package-path bash --package cabal-install to get a shell with cabal new-build
