Just so everyone has a clear view of what locations we're talking about:

On a related note: those Linux locations come from qtdiag of a Qt installed into /opt/local, actually a Linux build of the aforementioned qt5-kde port (MacPorts package).
I'm surprised that I'm not seeing /opt/local show up anywhere in there. What would be the consensus to modify in these locations, for a Qt installed into /opt/local where KF5 could also be installed? Replace everything pointing to /usr/local with /opt/local, or also replace /usr with /opt/local?
