--- Comment #2 from kpaasial at gmail.com ---
It's not possible to know in advance that port B doesn't need recompilation.
Any change in port A might cause a change in port B requiring a rebuild of B
and it's not possible by programmatic means to judge that in advance. The only
way is to rebuild B with the updated port A and then see if port B actually
changed. This also applies recursively so if you now have a port C that depends
on B you must recompile port C as well.

This is not a pkg issue, it's a feature of the ports system and package
builders such as poudriere.
