Comment (by ryandesign@…):

 Indeed, I see the same for mysql56 on my system. Indeed, the Portfile is
 doing this intentionally:
 {{{
     if {[string match *clang* ${configure.cxx}] &&
               ${os.major} >= 13} {

         configure.args-append \
                         -DCMAKE_CXX_FLAGS:STRING="-stdlib=libstdc++"
     }
 }}}
 But the Portfile should presumably be using the new variable available in
 MacPorts trunk to indicate this, if possible.
