[Nix-dev] how to disable tests

[Christopher Howard]

Hi. I'm trying to build emacs-24.2, but I can't because guile-2.0.7
won't build. One test failed. Personally, I don't care. (Coming from a
Gentoo background, I know that half the packages out there with unit
tests will fail their tests even though the software works fine, which
is why tests are not enabled by default in Gentoo.) How do I run Nix
with tests disabled?
