Error installing qt5-qtwebengine

[Bachsau]

Hi, I tried to install qt5-qtwebengine as a dependency for py34-pyqt5. This is the output I got:
--->  Computing dependencies for qt5-qtwebengine
--->  Staging qt5-qtwebengine into destroot
Error: No files have been installed in the destroot directory!
Error: Please make sure that this software supports 'make install DESTDIR=${destroot}' or implement an alternative destroot mechanism in the Portfile.
Error: Files might have been installed directly into your system, check before proceeding.
Error: org.macports.destroot for port qt5-qtwebengine returned: Staging qt5-qtwebengine into destroot failed
Please see the log file for port qt5-qtwebengine for details:
