 Replying to [comment:5 RobK88]:

 non-universal variant if `expat`.  But the port fails at the build stage.

 Ok, this is a second and completely unrelated problem. The problems in
 that log start with:

 {{{
 Undefined symbols for architecture x86_64:

       __ZNSt3__127__throw_bad_optional_accessB7v160006Ev in

 }}}

 According to #68220 this will happen on any macOS version earlier than
 10.13 because those libc++ versions are too old. The legacy support
 portgroup has a feature to let a port use a newer libc++ from MacPorts
 instead. I do not know whether using that would have other undesirable
 consequences.
