Comment (by Ionic):

 Err, actually, that only holds for systems using libc++ and are not too
 old.

 We'd really have to reimplement the cxx11-1.1 PG in `dvisvgm`, because we
 naturally want to keep ppc machines on gcc-6 of course.

 So rather something like

 {{{
 if {${configure.cxx_stdlib} eq "libstdc++"} {
   if {(${os.platform} ne "darwin" || ${os.major} >= 10) && ${build_arch}
 ne "ppc" && ${build_arch} ne "ppc64"} {
     compiler.whitelist macports-clang-6.0
   }
 } else {
   compiler.fallback-append macports-clang-6.0
   compiler.blacklist-append {clang < 600} macports-clang-3.* macports-
 clang-4.0 macports-clang-5.0
 }
 }}}
