Failed build from https://holochain.love

When I run nix-shell https://holochain.love, stuff happens for a while and then I get this message:

error: build of '/nix/store/0kgpachngcafm1isknpc88qdk1kif3a5-hn-release-hook-version-readme.drv', ... , '/nix/store/r495wj0fi274dd5b2c2xgnr07vm99xjz-hn-rust-flush.drv' failed

Here's the whole output from where it looks like things went wrong:
