Comment (by barracuda156):

 UPD. Yeah, this works:
 {{{
 platform darwin {
     if {[string match *gcc* ${configure.compiler}] || ${os.major} < 13} {
         # Older OS do not support native API, but GCC gonna fail anyway:
         # g++-mp-12: error: unrecognized command-line option '-fobjc-arc'
         patchfiles-append \
                     patch-older-macos.diff
         depends_lib-append \
                     port:fontconfig
     }
 }
 }}}

 {{{
