[Nix-dev] IHaskell on nixos

[Carlo Nucera]

Hi, does anyone know how to run ihaskell notebook on nixos?

The naive installation via `nix-env -iA nixos.pkgs.ihaskell` doesn't
work for me, I get the following error:
---------------------------------
> ihaskell console
Updating IPython profile.

Exception: /home/carlo/.ipython/profile_haskell/ipython_config.py:
openFile: does not exist (No such file or directory)
---------------------------------

I tried removing the locally created folders .ihaskell and/or
.ipython, but the error persists. I think there could be a problem
with the interaction with my local `.nixpkgs/config.nix` file, which
is this:

Do you have any idea on how should I install it?
