Comment (by rmottola):

 Possibly the initial error was spurious.
 I understand that libc++ needs to be excluded, but is fine for intel.
 Shouldn't it be written like this then, instead of forcing os < 9? Once it
 will work on PPC and/or PPC64 just remove the later tests

 {{{
 if {(${os.platform} eq "darwin" && ${os.major} < 10) && !(${build_arch} eq
 "ppc" || ${build_arch} eq "ppc64")} {
     depends_lib-append port:libcxx
     configure.cxx_stdlib libc++
 }
 }}}
