Well, this isn't technically exactly what it checks. Probably better to have something like:

    echo "WARN: Probably misconfigured GOPATH"
    echo "(no src/ directory found at GOPATH root)"
    echo "Your buildblast repository must be at <anything>/src/buildblast/"
    echo "as this is a requirement of the go compiler toolchain."
    echo "if <anything> == GOPATH, then the go tools will work as well."

Or something. I don't know.
