Comment:

 We've seen this `use of undeclared identifier 'sv_undef'` error before
 with other perl software; see for example #43112. However the cause may be
 different here.

 We have binaries of this port built for all versions of macOS, including
 Catalina. So at least we know there was not a general problem building
 this port back when those binaries were built. Do you know why your
 computer is trying to build this port from source rather than downloading
 our binary?
