There is no Howto for the QT4 and QT5 issue In the UPDATING file of the ports collection we can read this: 0170218: AFFECTS: users of Qt 4 and Qt 5 AUTHOR: kde@FreeBSD.org Following what is already done in Qt 5, the Qt 4 ports no longer install their binaries into ${LOCALBASE}/bin (which is "/usr/local/bin" in most cases). Additionally, the "-qt4" suffix has been dropped from the file names of the binaries that had it, such as "qmake-qt4". The new misc/qtchooser port is now used to choose whether a Qt 4 or Qt 5 version of a binary such as "moc", "qmake" or "designer" will be used. By default, the Qt 5 versions are preferred, but that can be changed by setting the QT_SELECT environment variable to "qt4". qtchooser also allows one to seamlessly use other Qt installations for those binaries, which is particularly beneficial to people working on Qt itself or who need their own checkouts. See qtchooser(1) for more information on how to configure qtchooser. Okay, fine. But, HOW TO do this?! I cannot install this qtchooser, because it bites with some qt4 ports that are installed. And I cannot deinstall them without deinstalling A LOT of dependencies - like kde. So please, WHAT is this for an issue in the UPDATING file? Is that kidding? There is no sollution?! We need a HowTo - where is it?

First for KDE people to address it, it should have been assigned to them, now it is is too late.
