cabal: cannot configure monads-fd-0.1.0.0. It requires transformers >=0.2
For the dependency on transformers >=0.2 there are these packages:
transformers-0.2.0.0. However none of them are available.
transformers-0.2.0.0 was excluded because transformers-0.1.4.0 was selected
instead
transformers-0.2.0.0 was excluded because control-monad-failure-0.6.0 requires
transformers >=0.1.4.0 && <0.2
