How can I install an older version of a port _and_ similarly old versions of all of the ports's dependencies?

Thank you, this is exactly what I wanted! Sources.conf was the missing piece I needed.

The one I'm currently having issues with is Docker Machine, which can't be installed due to an issue in Go and/or the Legacy Support framework (ticket #60611). I remember installing Docker Machine from Macports at some point in 2018, so it definitely used to work, and I wouldn't mind using that two-year-old version now—but I don't know how!

However, what I want to do is install an older version of not just Docker Machine, but all of the packages that Docker Machine depends on, so I'm not trying to compile a new version of Go with an old version of the Legacy Support Framework, or vice-versa. Is there a way to do that?
