MacPorts just ran rev-upgrade for you.
There's not enough information in the above output to know why py36-tables and octave were considered broken; we would need to have seen debug output (-d) to have made that determination.
But if MacPorts no longer shows these ports as broken, then the problem has been solved for your computer at least (and since the broken ports have been rebuilt and are no longer there, we can't make any further analysis of that the problem with them might have been).

If you want to switch mpich-default to that variant, yes. I'm not sure why the note the port displayed did not tell you to use "--enforce-variants"; that would seem to be necessary to achieve the intended result. Eric, Sean?
