 this is due to old nm being used. I applied a fix proposed by @kencu in
 another port and it works:

 {{{
 if {${os.platform} eq "darwin" && ${os.major} < 10} {
     depends_build-append port:cctools
     configure.env-append NM=${prefix}/bin/nm
     configure.args-append lt_cv_path_NM=${prefix}/bin/nm
 }
 }}}

 I put it in the subport section, before post-configure
