Qt::endl is only available since Qt 5.14 (​https://github.com/qt/qtbase/commit/461e89ee1a53).

I am only inclined to suggest dropping support for Qt 5.13/macOS 10.12 from the pyside2 port. Nobody seems to have already reported this issue, even though it has been present since pyside2 5.15.0 (​https://github.com/pyside/pyside2-setup/commit/870b7f4) which MacPorts updated to over 3 years ago ([4985db382c60/macports-ports]).
