Alternately, we would have to make each of those ports declare dependencies on each of the utilities it opportunistically uses, even if they're not necessary. Either solution means modifying hundreds or thousands of ports, and ensuring that newly added ports follow this strategy too. So far, we've been unwilling to do this.

When running port upgrade outdated, couldn't base just deactivate those utilities, upgrade them first and unattended rebuild broken ports/files, which is what the user eventually does manually?
