Resolving dependencies...
cabal: Could not resolve dependencies:
trying: ocaml-export-0.6.0.0 (user goal)
next goal: template-haskell (dependency of ocaml-export-0.6.0.0)
rejecting: template-haskell-2.12.0.0/installed-2.1... (conflict: ocaml-export
=> template-haskell<2.12.0.0)

After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: template-haskell, ocaml-export
