Comment (by kencu):

 I do have both bison and flex installed via MacPorts, and looking at my
 successful build log on Catalina, these are likely being used over any
 system versions:
 {{{

 }}}

 so try installing bison and flex, and if your build succeeds the most
 benign thing to do would be to add bison and maybe flex as build deps if
 they aren't already in there somehow.
