For some reason `gem install` unsets the GEM_PATH environment variable internally unless the install dir is provided. This in turn means that if it invokes extconf.rb and extconf.rb depends on a gem available on the GEM_PATH (like pkg-config for nokogiri) then it's not available in that context.

This is a hack that sets the :install_dir to where we would install anyways (the GEM_HOME is the default installation destination).
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.
