 }}}

 This is because during configuration net/if.h (which defines
 `IF_NAMESIZE`) isn't detected, so `HAVE_NET_IF_H` isn't defined and
 net/if.h won't be included by source files:
 {{{
 checking for net/if.h... no
 }}}

 Without digging into the configuration check, I'm inclined to think this
 is similar to #55238 where sys/socket.h needs to be included when using
 net/if.h on 10.8 and earlier; a future release of legacysupport will
 include sys/socket.h automatically ([ea4b467559/macports-legacy-support]).
