[Nix-dev] Debugging callPackage builds?

[Anand Patil]

Hi everyone,

I'm trying to debug
https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/compilers/ghcjs/default.nix
,
which is a callPackage-style Nix function that expects lots of arguments.
Is there a quick way to get a nix-shell or other type of debugging
environment for such a package?

Thanks,
Anand
