Comment:

 It failed with the same error on the 10.8 and earlier buildbot workers but
 succeeded on the 10.9 and later workers.

 Comparing the buildbot logs, the only difference between the 10.8 and 10.9
 configure phases is that 10.8 couldn't find net/if.h:

 {{{
 -- Looking for net/if.h
 -- Looking for net/if.h - not found
 }}}

 while 10.9 could:

 {{{
 -- Looking for net/if.h
 -- Looking for net/if.h - found
 }}}

 net/if.h exists on 10.8 and is where `IFNAMSIZ` is defined.

 Can you attach your config.log so that we can investigate why it couldn't
 find net/if.h? I suspect a necessary header has not been included. I
 recall this being a common problem on 10.8 and earlier.
