Build.sh fails

[prestonvanloon]

I guess there are some prereqs that are missing. Some Go packages that I am missing?

To reproduce:

Following quick start guide 1: ./docker-build.sh 2: ./build.sh <- fails

If I clone this repository to $GOPATH/src/github.com/kasey/grpc-example then the build.sh step works.

But now ./run.sh fails.

./run.sh
