Nope.  That's a toolchain bug; clock_gettime should be declared in
/usr/incude/time.h but apparently on the Mac it is not.  Attempted
fix pushed to repo.

Confirmed fixed in new clone.  'scons check' is successful.

This version/notice info is in "time.h":

 *      @(#)time.h      8.3 (Berkeley) 1/21/94

There is also an Apple header copyright notice dated 2000.

Just an FYI for future reference - the Apple developer tools are installed with Xcode in the following path:  "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include">

Thanks,
