Error When Trying to Create Implementation of Go-Etherieum

Hey all,

Apologies for this newbie question. I want to set up a basic Dapp, but can't seem to get an implementation of Go-Etherieum working on my local computer. I am following this helpful build guide: http://forum.ethereum.org/discussion/905/go-ethereum-cli-ethereal-simple-build-guide-for-osx. However, I keep getting the error "-bash: go: command not found" when I run the commands "go get -u -v github.com/ethereum/go-ethereum/ethereal" or "go get -u -v github.com/ethereum/go-ethereum/ethereum."

I have go-1.2.2 installed properly, along with the necessary dependencies.

Thanks!
