安装golang程序包后，它不起作用

I'm new on golang. According this instructions, to install go-bindata, I should use this command:

$ go get -u github.com/jteeuwen/go-bindata/...

I did it. After that, I checked on $GOPATH/src/jteeuwen/go-bindata/ and there's a file go-bindata.a. It seems like it was installed, but it doesn't work:

$ go-bindata
-bash: go-bindata: command not found

Please, what am I doing wrong?

EDIT: I'm using OS X

You'll need to add $GOPATH/bin to your $PATH.
