Hyperledger Fabric: cp: cannot stat ‘build/docker/gotools/bin/protoc-gen-go’: No such file or directory

Question

I have referred to this guide: http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#option-1-vagrant-development-environment

When trying to 'make peer', the command is as follows:

vagrant@ubuntu-1404:/opt/gopath/src/github.com/hyperledger/fabric/devenv$ cp: cannot stat 'build/docker/gotools/bin/protoc-gen-go': No such file or directory
