It builds for me with 1.3 (linux/amd64) on Ubuntu, so I'm guessing it somehow works on Linux but not Mac.
EDIT: Specifically, the first two lines are complaining about an undefined syscall and the next two are complaining about something terminal-related being 64-bit where 32-bit is expected, so those certainly seem like plausible things that would differ across OSes.
