Comment (by kencu):

 The issue could be here
 <https://github.com/zeromq/libzmq/commit/0dfb32a2595e96bd5850987c7cab9a7936e672e8>

 this guard block
 {{{
 #if defined ZMQ_HAVE_OSX && __MAC_OS_X_VERSION_MIN_REQUIRED < 101200 //
 less than macOS 10.12
  +    int rc = alt_clock_gettime (CLOCK_MONOTONIC, &tv);
  +#else
       int rc = clock_gettime (CLOCK_MONOTONIC, &tv);
  +#endif
 }}}

 might not be working correctly for Leopard, because Leopard should not be
 seeing that function call, it appears. Why don't you try forcing
 `alt_clock_gettime` to be used and see if that fixes it?

 for a quick one-off way to do that, port -v configure it, go into the
 source, and monkey with that file like so maybe:

 {{{
 int rc = alt_clock_gettime (CLOCK_MONOTONIC, &tv);
 }}}

 then try building. If it doesn't work, look for other guards that might
 need fiddling with.
