I think we should use cxx_stdlib as one additional criteria to respect when selecting an archive site here: https://github.com/macports/macports-ports/blob/master/_resources/port1.0/fetch/archive_sites.tcl https://github.com/macports/macports-base/blob/995dde8476c48580db4f6eedfde09e90dc5e8c99/src/package1.0/portarchivefetch.tcl#L66 Then the archive site would no longer be used if anyone changes the default in macports.conf.
