The magic of installing the required dependencies happens in
Mk/Scripts/do-depends.sh.
If something like this had to be done, it should be hooked in there.
Keep in mind that unless you are extremly lucky (as in, it'll never
happen), the packages you will be fetching will not match the ports tree
you are using, and it will most probably not work correctly.

It is the main reason why a feature like this was never added. It will
only ever bring pain and suffering to those who use it because unless
used in an experimental and controlled setting where you build the
packages you need from your ports tree, and then use that repository to
install them, it will never give you the correct packages for your ports
tree.  And if you are doing it, well, poudriere already does all this
and I do not see a reason to try and do in in some strange other way.
