[Octave-bug-tracker] [bug #57821] [geometry] Test failures on macOS

[Andrew Janke]

Follow-up Comment #1, bug #57821 (project octave):

Oops; a bad verbatim tag snipped off the rest of my post.

Under Octave 5.2.0 on macOS 10.14.6, I'm getting some test failures.

For the first one, maybe Python 3 is widespread enough that you can't expect a
specific python3 command to exist?

For the second one, maybe this is a load order/shadowing issue between the two
clipPolygons in geometry and matgeom?
