Comment (by mojca):

 Replying to [comment:5 jwhowse4]:
 > I have the `webkit2-gtk` port installed.  When I deactivate it,
 wxgtk-3.0 builds without error.  Thanks for the suggestion.

 Thanks a lot for confirmation. We have two unrelated bugs. The first fix
 has been suggested by Ken (to avoid the break in your case; I would patch
 `configure` itself though). The second bug is on our side, that's
 opportunistic usage of `webkit2-gtk`. We should figure out if this
 dependency is needed/useful and either make sure that it's not used, or
 make it a dependency of the build. I have no clue myselfy, but apparently
 no other user missed it so far, so maybe we can simply disable it?
