1. If you have a computer with Nix installed, you can build
libffcall.src and then just "nix-store --export" the path.

2. Something like
stdenv.mkDerivation {
  buildCommand = "sleep 1d || true";
  sha256 = "...";
  name = "..";
}

Copy predownloaded checkout to $out, kill the sleep (there are cleaner
ways to do this, though). Should be enough.

3. Adding something.src to Hydra when a redistributable src is obtained
non-trivially
seems a good idea.. What do others think?
