Comment (by JanWielemaker):

 Of course it is fine to fix this using some option in the Portfile.   That
 should be tested by others though.   My Mac runs the latest version of
 MacOS.   I prefer this solution.

 Alternatively, one could use the CMake option `-DSWIPL_PACKAGES_cpp=OFF`
 in the Portfile if we knew the affected platforms.

 The only thing I consider acceptable for SWI-Prolog's source is a CMake
 test and disable affected functionality.   Note that the C++ interface is
 not vital for SWI-Prolog and the detail affected by this error has very
 little impact.
