This came up in reinstalling everything after moving to Big Sur, mlt is not requested.

Several ports have needed QPainterPath.h added:

Should be fixed in pull request ​https://github.com/macports/macports-ports/pull/9577 I was able to build and test with Qt 5.15.2 on my macOS 10.14 machine, but my only Big Sur machine at the moment is M1, for which qt5 ports fail on icu dependency.
