[Nix-dev] Guidance on packaging extended-reals

[Carlo Nucera]

I'd like a suggestion on what to do with the haskell package
extended-reals (https://hackage.haskell.org/package/extended-reals),
which, when I to package it, yields this error:
http://lpaste.net/115721.

I'm using, to install, a variant of this Fuuzetsu's config.nix:
https://github.com/Fuuzetsu/nix-project-defaults/blob/master/nixpkgs-config/config.nix

I gather that the problem is in the fact that the package Quickcheck
is needed by the test suite, and I'd like to learn how to diagnose and
solve this kind of problems.

So, if you have a suggestion, it would be very appreciated.
