During handling of the above exception, another exception occurred:

A guess is there's a Python 2 versus Python 3 mismatch somewhere (only
Python 3 is intended to be supported now). Try checking symbols in
the SubnetTree module via `nm /opt/zeek/lib/zeek/python/_SubnetTree.so

grep -i "init_"` and it should show "_init_SubnetTree" for Python 2

and "_PyInit__SubnetTree" for Python 3.

Looking at the output of Zeek's `./configure` may also help show
what's happening with the SubnetTree module and Python generally. If
you have other basic info for reproducing like OS/environment, that
can also help.

Thanks for this. Turns out I needed the dev package for python3.
