Created attachment 173282 [details] patch to unregister net/qt5-enginio net/qt5-enginio expired on 2016-08-04 but is registered in Mk/bsd.qt.mk so remove it from there. An INDEX build with qt5-enginio unregistered and removed showed no problems.
Looks good to me.
A quick git grep enginio doesn't show any port using it, so go ahead.
