curl fails to build due to old nm

[rmottola (Riccardo)]

On Leopard, curl fails to build, with the known "NM" error.

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

This still applies... and still works!

I'll take your word for it!
