py*-opencv3 use the wrong python

[jmroot (Joshua Root)]

All subports appear to be trying to use the same python as opencv3, but only one happens to depend on that version (currently py311-opencv3). For example py27-opencv3 fails like this:

and likewise py310-opencv3:

Egads... this is indeed an issue, confirmed via trace mode. Still need to determine root cause though.

Thanks for the heads-up Josh!
