We don't support building ports against old versions of dependencies. We don't support users that choose to do this with "-n" or "-p". If a dependency is not supported on a particular system, MacPorts should fail to build it and will not proceed to build the dependent.

There is no supported situation in which a dependency does not upgrade to the latest version before dependents are built.

This is not a supported use case.
