Comment (by erikbs):

 Somehow I missed this ticket when I opened my PR and therefore did not
 reference it, but the issue disappeared when I added legacy-support to the
 Portfile:
 https://github.com/macports/macports-ports/pull/18179

 The port also seems to build fine when linking against libstdc++ instead
 of libc++, but since the legacy-support approach was much easier, I went
 with that.
