Comment (by kencu):

 Peter, that's essentially the botan fix I mentioned:
 {{{
 # add the selected -stdlib to clang builds
 # see https://trac.macports.org/ticket/53123
 if {[string match *clang* ${configure.cxx}]} {
     configure.cxx ${configure.cxx} -stdlib=${configure.cxx_stdlib}
 }
 }}}
 Could you try that please, and if you confirm it works, we can add it to
 the Portfile.
