Comment (by kencu):

 Hi John; the referenced commit did not change `gnucash` to link into
 `webkit2`; `gnucash` still links against `webkit1`. Some older systems
 were previously forced to use an old version of `webkit1` due to toolchain
 issues with `c++11`. We sorted that out, and MacPorts' last available
 version of `webkit1` now builds on all systems (except PPC), so we now use
 that version for all systems in ports such as `gnucash`.

 We all hope that one day `gnucash` might no longer need `webkit1` and will
 either use the more-up-to-date `webkit2` or some other javascript
 implementation. We look forward to hearing from you / finding out about
 this when this is possible.

 MacPorts has evolved a somewhat confusing array of `webkit` builds over
 time, which we are trying to simplify.

 We recently updated our `webkit2` offerings on MacPorts; `webkit2-gtk`
 offers version 2.20.3, and `webkit2-gtk-devel` offers 2.21.4. Perhaps one
 of these versions might pass your tests and we could eventually default to
 using one of them instead.
