Hi Alan,
I did a `cabal clean && cabal configure`, then a `cabal clean && cabal
configure && cabal build`, and just to be sure I reinstalled all my
haskell environment. The package gets installed in ghcWithPackages,
but I still have that error inside emacs with ghc-mod.

Is there anything else I could try?
Best regards
