He obviously wasn't clear enough about this, but if you're just trying to use the tool, download the binary release. Don't use go get as an installer. They're trying to be multi-OS compatible, an autotools that doesn't assume every system has a /usr/local or whatever the Windows equivalent but not assuming everyone has a %USERPROFILE%\AppData\Local\Low\Roaming or whatever. It does assume everyone has a home directory and an environment variable indicating where that is.
