Comment (by RJVB):

 Much easier said than done, alas. At least the way I build and install my
 KF5 stuff but even if I didn't try to get feature parity with Linux builds
 there would still be a sh*load of dependencies to introduce first. Here's
 a pruned list allowing to focus on non-existant ports (kf5-*):
 ```
 The following ports are dependencies of kf5-digikam
 @7.1.0_0+langselect+qt5kde:
   xz
   pkgconfig
   cmake
   kde-extra-cmake-modules
   kf5-kdoctools
     kf5-ki18n
       python27
       qt5-kde

         kf5-kdeclarative
         kf5-kirigami2
           kf5-breeze-icons
     shapelib
   libgpod
   ImageMagick
   eigen3
   lensfun
   libgphoto2
   gphoto2
   liblqr
   kf5-libkexiv2
   oxygen-icons
   qt5-sqlite-plugin
     qt5-qtbase
   gstreamer1-gst-libav
   gstreamer1-gst-plugins-good
 ```

 Personally I have given up on the idea of introducing KF5 to MacPorts -
 I'm not even maintaining my own ports very actively anymore.

 Gilles himself probably has experience building a standalone version using
 a script he might be able to tweak so Qt5 and other dependencies are taken
 from MacPorts but the KF5 frameworks and libraries are embedded in the app
 bundle.
