+Octave can use either Qt4 or Qt5, and it will select Qt5 if both are
+installed.  You can force it to use a particular version by passing QT=4 or
+QT=5 to the script.  If Qt5 is selected and it does not find a Qt5 version of
+QScintilla, then the editor window in the GUI will be disabled.  If you need
+the editor window and have both Qt versions installed, force it to use Qt4.
 
 Octave can use ImageMagick (part of Slackware) or GraphicsMagick (available
-from SBo) for some functionality.  ImageMagick 6.8.6-10 from Slackware 14.1

+GraphicsMagick will be selected by default, since ImageMagick is not

 If you have arpack installed and the configure script segfaults when trying to
