octave @5.1.0_0+accelerate+app+docs+gfortran+graphicsmagick+qt5+sound+sundials --- Compiler error issue with qt5's "posF"

[SenileFelineS]

I'm trying to install octave (see title) with the qt56 dependency.

I received two errors caused by the same issue of not recognizing 'posF':

(Error 1)

  CXX      libgui/graphics/__init_qt___la-ToolBar.lo
libgui/graphics/Canvas.cc:398:57: error: no member named 'posF' in 'QMouseEvent'; did you mean 'pos'?
            bool rect_contains_pos = r.contains (event->posF ());
                                                        ^~~~
                                                        pos
/opt/local/libexec/qt5/include/QtGui/qevent.h:115:19: note: 'pos' declared here
    inline QPoint pos() const { return l.toPoint(); }
                  ^

(Error 2)

libgui/graphics/Canvas.cc:452:61: error: no member named 'posF' in 'QMouseEvent'; did you mean 'pos'?
                bool rect_contains_pos = r.contains (event->posF ());
                                                            ^~~~
                                                            pos
/opt/local/libexec/qt5/include/QtGui/qevent.h:115:19: note: 'pos' declared here
    inline QPoint pos() const { return l.toPoint(); }
                  ^

These two errors both reference the qt5 library file /opt/local/libexec/qt5/include/QtGui/qevent.h:115:19 which does in fact make reference to posF() as the following:

#if QT_DEPRECATED_SINCE(5, 0)
    QT_DEPRECATED inline QPointF posF() const { return l; }
#endif

However, I have no idea if that matters.................I'm guessing it actually doesn't.

I've attached both the build main.log and the qt5 qevent.h files.

Thank you.

The qt5 file that defines pos() but apparently not posF()
