 After just updating all of my outdated ports, `sphinx-build-3.x` is now
 failing.

 For example, the output from `sphinx-build-3.9` is as follows. (Note that
 `sphinx-build-3.8` is failing with an identical set of errors, apart from
 the python pathnames.)

 }}}

 Based on the stack trace, it almost appears as if there's a version
 mismatch relative to `py-idna`. But perhaps this is only a side-effect, of
 a mismatch further down the dependency tree?

 Assigning to Josh initially, since he's the `py-sphinx` maintainer...
