     Type:  defect       |     Status:  assigned
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.8.1
 Keywords:               |       Port:  qt513-qtwebengine qt5-qtwebengine
                         |  qt6-qtwebengine
-------------------------+-------------------------------------------------
 The ports for qtwebengine 5.13, 5.15, and 6 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.
