Yes, you're right. This is the ticket you filed last time: http://hackage.haskell.org/trac/hackage/ticket/227 and my comment: One problem is that not all build-tools correspond to haskell packages. Some do some don't. We have a hard coded list of them at the moment (which can be extended in Setup.hs files) so we could extend that with what haskell package if any the tools correspond to. Any better suggestions to make it a tad more generic? If anyone has a godd suggestion I'm happy to hear it. Otherwise we can just add a Maybe Dependency to the Program type to indicate that some build tools have a corresponding haskell package.
