Comment (by michaelld):

 As noted in the Volk 2.5.1 issue (https://trac.macports.org/ticket/65377),
 and applicable here: What to do here? I'd love a more universal solution
 for the libc++ issues. We have this Volk one (std::filesystem) as well as
 the recent Doxygen one. We can try static linking of MP-libc++.a, but that
 will currently be a one-off solution for each port. It'd be great if we
 could somehow just move MP to use the MP-libc++.dylib ... @kencu is
 probably the most knowledgable about this! Do we have a MP ticket up for
 this discussion already? If so then we can tag it here & close this issue.
