 Replying to [comment:2 RJVB]:
 > Why the F••• does this have to be so difficult, is it really your
 intention to make it impossible for me to ensure that port:qt5-kde can act
 as a drop-in replacement for the regular Qt5 ports?!
 After taking some time to better understand
 [https://github.com/RJVB/macstrop/blob/master/aqua/qt5-kde/Portfile
 qt5-kde] and
 [https://github.com/RJVB/macstrop/blob/master/_resources/port1.0/group/qt5-kde-1.0.tcl
 qt5-kde PG], I believe you perceive difficulty because there is a
 fundamental difference of opinion of what constitutes a
 [https://en.wikipedia.org/wiki/Drop-in_replacement drop-in
 replacement].[[BR]]
 Just as a simple example, qt5-kde and qt5-qtbase  install their header
 files in [https://github.com/macports/macports-
 ports/blob/eee9bd65ab3bc1f0907a51b41b7cb6938ce05756/_resources/port1.0/group/qt5-1.0.tcl#L194
 different]
 [https://github.com/RJVB/macstrop/blob/514f77d986c46bdee97cf12aa5c16d442083a51d/_resources/port1.0/group/qt5-kde-1.0.tcl#L285
 locations].[[BR]]
 Perhaps KDE requires this design choice, but it means that qt5-kde is not
 a drop-in replacement.

 Is qt5-kde to be drop-in replacement in the strict sense (same library
 names, same header names, same layout, etc.)?[[BR]]
 If so, then we already have the infrastructure to proceed.[[BR]]
 If not, then there is no reason to jump through so many hoops trying to
 convince Portfiles that it is.[[BR]]
 Confusion on this fundamental question has led to countless delays and,
 apparently, a fair bit of frustration.
