Comment (by Ericson2314):

 Hmm, this may be a cabal my error, but I nuked my `~/.cabal/cache`, did a
 `cabal new-configure --extra-lib-dir=.*`, and the package conf for
 `digest` in the new cache still didn't have `library-dirs: ...nix's-zlib`,
 causing a failure when GHCi attempted to load `digest`.
