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?

R.
