In case anyone worries, I'm fine, thanks for your concern.

A fix for bootstrapped-pip is in staging because its a mass-rebuild. Let's hope it won't break other stuff.

As of cd4d0c72a8, this is still failing.

Ah, never mind; user error on my part. Sorry for the noise.

If you're curious, I should have run NIX_PATH=nixpkgs=$HOME/src/nixpkgs nix-shell -p nox --run zsh. The nix UI could really use some improvement.
