this issue is described in https://github.com/NixOS/nixpkgs/issues/7792. Instructions how to recover from this problem are in this thread. The short version is: garbage collect "haskell-clientsession" and all its dependents, then download those packages from scratch (or build them locally with --option build-use-substitutes false. Anyway, the ticket has more information on this subject.
