[__5] fail (backjumping, conflict set: PropaFP, ghc, template-haskell)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: template-haskell, exceptions, PropaFP,
ghc, transformers, base, temporary
Try running with --minimize-conflict-set to improve the error message.
