 Oh, I see. But -Rf is not right, it also recompiles zillions of
 non-Haskell packages.

 In practice, just installing zlib manually via cabal worked
 here. I think the right port command would be

 {{{
 port  -fun upgrade hs-zlib
 }}}

 and repeat for each port that represents a hackage
 package.

 But you don't want all dependents, just those that
 are hackage packages. We need some way to get
 a list of those.
