[Nix-dev] libreoffice problems

[Sergey Mironov]

Hi. Something weird has happened with libreoffice package. Were I
include it in the
environment.systemPackages, nixos is going to rebuild just about all it's
dependencies. Here is the incomplete list of what are about to be built:

(total >100 packages)

I doesn't look like 'normal' hydra build failure. What do those
double-hashed derivations mean?

I'm on current nixpkgs tree, and have no packages
installed via nix-env also. Any ideas?
