Comment:

 Replying to [comment:1 jmr@…]:
 > Ideally there would be a general check that the arch(s) being built for
 matches what all the deps were installed with,
 Ah yes. That would be a better generalization. When building for an arch
 (or archs), bail if dependencies don't have that arch (those archs). This
 implies we need a way for ports to store in the registry what archs they
 were built for.

 Need an exception for noarch ports: they should record not the build arch
 but "noarch". This implies we need a way for ports to indicate they are
 noarch -- #12206, also #20739.

 > and we would try to add the needed arch(s) if not present.
 I would skip that suggestion for now; it adds more complication, and this
 is already complicated enough. We can do that later, separately. For now
 it would be fine to bail with a good error message.
