GHCJS uses integer-gmp, but cabal2nix generates a dependency list that includes integer-simple instead. This tweaks the stage2 generator to replace any instance of integer-simple with integer-gmp. Things currently still work without this change (assuming integer-simple is defined as null), as ghcjs includes integer-gmp in its stage1 packages - so it's always available. However, this change makes things a bit more explicit, rather than leaving things to chance. If at any point the stage1 packages are also split up into separate derivations, the integer-gmp package will need to be passed along to the packages that depend on it. This change should prevent some confusion going forward.
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-15.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-15.09
For pull-requests, please rebase onto nixpkgs master.
NixOS linux distribution source code is located inside
nixos/ folder.
