Notice the depends which has an extra : after auth.

When running zef --debug info -v 'DateTime::Timezones:ver<0.4.1>:auth<zef:guifa>' that dependency is not listed:

- Info for: DateTime::Timezones:ver<0.4.1>:auth<zef:guifa>
- Identity: DateTime::Timezones:ver<0.4.1>:auth<zef:guifa>
- Recommended By: Zef::Repository::LocalCache
- Installed: No

I would have expected some kind of error hinting at the malformed dependency spec.
