Yes, this update needs to be done. The reason for my delay in doing so is this statement in the release notes of 2.13.0:
This new release brings you a completely updated and enhanced ftinspect demo program, which now combines the functionality of almost all other graphical FreeType demo programs into a single application based on the Qt framework.
Qt of course depends on FreeType, therefore in MacPorts we cannot have FreeType depending on Qt. I have not yet investigated what, if anything, is needed to tell FreeType not to attempt to build this new Qt-based demo program, even if Qt is installed.
Later on, if desired, we could offer that demo program in a subport which would depend on FreeType and Qt.
