 If you need two packages, install them simultaneously:

 cabal install [--dry-run] happstack-server missingh

 This guarantees that they get installed with consistent dependencies.

 You're hitting an instance of ticket #371, that cabal can break existing

 change their request. (Or the long term solution is a persistent package
