 I have, however, built readline just fine as an arm64 library, so I'm not
 sure where it is flagged as unbuildable for this arch combination (I also
 looked at the readline/Portfile and I don't see any limitations flagged
 there).  Not sure what's up with this, but as readline is a very key leaf
 port, it is probably worth fixing.

Comment (by jmroot):

 If you're building on an Intel system, the problem is
 {{{
 merger_must_run_binaries yes
 }}}
 It would work on an arm system since that can run x86_64 code.
