Wait... PyQt5 is not in the FreeBSD ports collection?

Do I understand correctly that PyQt5 is not in ports, that you adapted the
PyQt4 port to build PyQt5, and that some native C++ calibre component is
failing to build against that PyQt5 installation?

If so, I'd say you're doing pretty well.  I would be glad to help with that
PyQt5 port.

Cheers,
Erik
