Comment (by mouse07410):

 > installing a the port for a different Python version is of course not
 going to solve your problem.

 Definitely not - because the very same error/problem occurs with
 Python-3.8 ''and'' Python-3.9.


 > however, when I install the {{{abseil}}} port from MacPorts, and run the
 build of py-grpcio on my Mojave system, it works.

 Thank you! This seems to be the key. And not the SDK (just like I said ;).
 After installing {{{abseil}}} port (probably versions matter, as my Python
 installation had {{{abseil}}} due to another package' needs, brought in
 via {{{pip}}}):

 {{{
 $ sudo port uninstall py38-grpcio
 Enter PIN for 'Certificate For PIV Authentication (Blumenthal, Uri
 (UR20980))':
 Note: It is not recommended to uninstall/deactivate a port that has
 dependents as it breaks the dependents.
 The following ports will break:
  py38-tensorflow_macos @0.1.alpha3_0
  py38-tensorboard @2.5.0_0

 Perhaps a dependency set should be updated for {{{py38-grpcio}}} and
 {{{py39-grpcio}}} to include {{{abseil}}} port?

 > BTW: the buildbot has finished building it, it seems, and there was
 success on all systems, so you can probably download the binary now if
 you're getting tired of this...

 Yes, thanks - that too. That's what I did with {{{py39-grpcio}}}. ;-)
