Comment (by iefdev):

 I tried building using the same compilers and they built, so I guess it's
 not that.

 I don't know if this is related, but this differed from my log:

 {{{
 :info:configure checking for -force_load linker flag... ld: unknown
 option: -force_load
 :info:configure no
 }}}

 On my system: `IPV6_TCLASS` is in `<netinet6/in6.h>` if that helps.

 {{{
 #!c lineno=428
 /* APPLE: NOTE the value of those 2 options is kept unchanged from
  *        previous version of darwin/OS X for binary compatibility reasons
  *        and differ from FreeBSD (values 57 and 61). See below.
  */
 #define IPV6_RECVTCLASS         35 /* bool; recv traffic class values */
 #define IPV6_TCLASS             36 /* int; send traffic class value */
 }}}

 It's not in
 [https://opensource.apple.com/source/xnu/xnu-1228.15.4/bsd/netinet6/in6.h.auto.html
 netinet6/in6.h.auto.html] //(via [https://opensource.apple.com/release
 /mac-os-x-1058.html 10.5.8])

 Perhaps it renamed, moved or somewhere else?
