Comment (by cnewbold):

 It appears that the macOS 10.12 SDK, which is what is used with XCode 8,
 defines both CLOCK_MONOTONIC and CLOCK_MONOTONIC_RAW which then causes
 Boost.Interprocess to follow the Linux branch and reach for clock_gettime.
 That works fine when actually running on a 10.12 machine, but 10.11 does
 not have clock_gettime so you get a busted executable that dies at runtime
 with an unresolved external.

 Unfortunately Apple does not condition the definition of these macros on
 the deployment target, so even telling XCode 8 that you're targeting 10.11
 results in references to clock_gettime.
