the situation will improve once the nixos-unstable channel updates [1]. At the moment, cache.nixos.org doesn't contain any Haskell libraries, but commit c5d132c2ea has changed that (or so I hope). It just hasn't reached the channel yet. Also, it's my understanding that "matrix builds" on Travis-CI actually run on separate virtual machines. Is that correct? If that is so, then building with 3 versions of GHC that way means installing and downloading the Nix environment 3 times for every commit, too, which seems rather wasteful.
