Hmm, can you turn on debug logging with --debug or similar?

Downloading dependencies like geckodriver currently requires a few tools like wget, curl, and tar. Is it possible one of those isn't on your PATH?

This situation will improve soon when we add support for obtaining things like geckodriver automatically via Nix.
