Concerning the error show at  https://paste.kde.org/p2vtxcfcs , it turns out that it indeed went away after I moved aside /opt/local/include/qt5 . That is the place the headers should go after installation, NOT where they should be looked for during the build. In other words, `configure -headerdir foo` should NOT, IMHO, add `-Ifoo` to the compiler/preprocessor options!

Can that be considered a bug? Can I safely do a search and remove of -I/opt/local/include/qt5 in the generated makefiles (or wherever that option is stored) before starting the build?
