https://github.com/NixOS/nixpkgs/pull/17555 added an override that pins the version of haskellPackages.hans to a specific Git revision. This means that any version updates in the Haskell packages set will have no effect and that our users will be stuck at that (arbitrary) version until the override is removed again. Furthermore, it's bad practice to distribute a package dubbed as version X when it's really version Y! The proper way to fix this issue IMHO is to convince upstream to released a fixed version to Hackage.
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels git://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-16.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-16.03
For pull-requests, please rebase onto nixpkgs master.
NixOS linux distribution source code is located inside
nixos/ folder.
