#69712: Broken upgrade to py312-contourpy @1.2.1 from @1.2.0

---------------------+-----------------------------
 I am attempting to upgrade to the most recent `py312-contourpy @1.2.1` and
 I run into several errors exemplified below. Errors are thrown in step
 5-13, 14 is never reported (I guess because of a `make -j 8` or similar).
 I noticed a reference to `pybind11` so I forced a rebuild of
 `py312-pybind11` to see if it helped, but it didn't.

 As `py312-matplotlib` depends on `py312-contourpy` I had to upgrade that
 port with `port -v -p upgrade py312-matplotlib` which builds with the old
 `py312-contourpy @1.2.0_0`.

 The first of several `kwarg` errors:
