notmuch @0.34 build fails with "ld: symbol(s) not found for architecture x86_64"

[rseichter (Ralph Seichter)]

I am in the process of bumping the mail/notmuch port to version 0.34 and see the following error messages:

cd bindings/python-cffi && \
  /opt/local/bin/python3.9 setup.py build --build-lib build/stage && \
  mkdir -p build/stage/tests && cp tests/*.py build/stage/tests

Any suggestions regarding how best to deal with this issue? I found a similar ticket ​https://trac.macports.org/ticket/63612 for "quassel", but I am unsure if this is something that can be fixed in notmuch's Portfile or requires an upstream change.
