Mark BROKEN: fails to build

cabal: Could not resolve dependencies:
[0] trying: MissingH-1.4.1.0 (user goal)
[1] unknown package: random (dependency of MissingH)
[__1] fail (backjumping, conflict set: MissingH, random)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: MissingH, random
