Comment (by kencu):

 yeah, that's it:
 {{{
 % port -v installed gmp
 The following ports are currently installed:
   gmp @6.2.1_1+universal (active) requested_variants='+universal'
 platform='darwin 22' archs='arm64 x86_64' date='2022-11-09T23:32:34-0800'
 }}}

 Unless somebody comes up with a better plan, for now you must install
 diffutils and then change muniversal to use it, by substituting
 {{{${prefix}/bin/gdiff}}} for {{{/usr/bin/diff}}}. I'll post up the diff I
 used, for short term fixes. But the definitive fix will need some
 pondering, as per the other ticket.
