Not running correctly with nix-build

[commandodev]

⇒  ./result/bin/stack2nix .

Ensuring git version is >= 2 ...
Ensuring cabal version is >= 2 ...
stack2nix: haskell.compiler.ghc843 failed to build via nix
CallStack (from HasCallStack):
  error, called at src/Stack2nix/Util.hs:79:22 in stack2nix-0.2.2-EtJJy0cFom33lozvs8RJ6L:Stack2nix.Util

Looks like this is trying to install ghc-8.4.3. Do I need to build stack2nix with the correct version or something?
