Comment (by cceleri@…):

 Ok. I was not aware of the -W option. Looks like it's right in front of me
 on the portfile(7) manpage though!

 Ideally the python27 dependency should be part of the python27 variant;
 I'm hesitant to role the variant into the normal installation since the
 bindings are not generally required to run notmuch on a daily basis. There
 are also bindings for ruby and go which I would like to support in the
 form of variants in the future too.

 I think an explicit python* dependency would be good for each python*
 variant since we will only need a particular python version to resolve the
 issue in #48667.
