I think this is because you are on an older version of Go. Try it with Go 1.3

I am using Go 1.3.

  $ go version
  go version go1.3 darwin/amd64

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.
