New description:

 The ports for qtwebengine 5.13 and 5.15 depend on MacPorts’ re2, but the
 configure test fails due to re2 now requiring Abseil which requires C++14,
 and so `-std=gnu++11` (presumably a default flag from qmake) as used by
 the configure test is not allowed.

Comment:

 To correct myself, qt6-qtwebengine is not affected by this (presumably
 since it uses C++17)
