 It got broken when the python portgroup's default value of `python.pep517`
 changed from `no` to `yes` for python versions 3.7–3.10
 [changeset:3173d46b9a29bc9d79ddb6970e7f083ebe3f79c0/macports-ports last
 year]. The fix for that would be simply:

 {{{#!diff

 }}}

 But I expect you're right that it also needs to be updated to build with
 cython 3. Subports for python 3.11 and 3.12 should be added then as well.
