It seems to me that buildbot is not broken on Darwin.
This build failure was referenced from a comment: https://hydra.nixos.org/build/243534318/nixlog/6.
I was able to successfully build, run and get a basic buildbot master, worker
and web ui going on my aarch64-darwin machine:
```
❯ nix run .#nix-info -- -m
- system: `"aarch64-darwin"`
- host os: `Darwin 24.0.0, macOS 15.0.1`
- multi-user?: `no`
- sandbox: `yes`
- version: `nix-env (Lix, like Nix) 2.91.1
System type: aarch64-darwin

The buildmaster appears to have (re)started correctly.
