Actually, when I tried to build from a fresh checkout from the jrconlin repo it failed b/c go *wasn't* automatically copied to $(GOBIN):

```
/bin/sh: 2: /home/rob/tmp/heka-build/bin/go: not found
make: *** [bin/hekad] Error 127
grail git:master ~/tmp/heka-build $
```

It only worked after I again uncommented out the `cp` command.
