/usr/bin/python will be removed in macOS 12.3!

[Gerben Wierda]

Well, yes, I kind of knew already that it was a terrible idea. Kind of felt terrible in the first place (was just checking).

But how does one (a) find out the dependency exists and (b) make sure the software finds python from MacPorts?

And of course, such a band-at only hides the debt that has now been created in the ports so it is a bad idea in other senses as well.
