While you can do this, there's really no reason to. All your package
depends on is any version of bedandbreakfast that the user can install.
cabal will prefer to install newer versions of packages over older ones, so
I don't think there's any situation in which adding this information to
your cabal file would allow your package to install when it otherwise

Your real problem, as you note, is just that bedandbreakfast 5 is not
available on hackage.
