Right - it is caused by gssapi, which will be built from source if there's
no binary wheel available for your platform. It's not clear what platform
you're on, but installing the krb5-devel (Redhat/CentOS/Fedora)
or libkrb5-dev (Debian/Ubuntu) should solve the build issue.

I'm not sure I understand the issue there. What prevents you from going
back to 4.29?

I'd need to dive into it some more. There are "extras", but from what I can
see these have to be explicitly installed. Ideally we want something that
will try to install gssapi automatically, but not get upset if it fails.
