Qt5 port unparsable: can't read "qt_archdata_dir": no such variable

[Vincent Habchi]

Folks,

every time I update my tree from svn I get this message:

“Failed to parse file aqua/qt5/Portfile with subport 'qt5-qtbase': can't read "qt_archdata_dir": no such variable”

And of course I cannot build Qt5. Has someone a clue?

Thanks,
Vincent
