Comment (by rlhamil):

 Replying to [comment:5 hapaguy]:
 > I suspect that this issue is related to a similar issue with
 qt5-qtwebengine (https://trac.macports.org/ticket/60978), which is caused
 by a bison 3.7 bug (https://trac.macports.org/ticket/60978#comment:3).

 I re-installed the older bison @3.6.4_0, and webkit-gtk3 built just fine
 with that, and subsequently deactivating it and reactivating the current
 bison didn't break anything either. So that probably confirms the general
 notion that something different about bison 3.7 is the problem.
