The plugin does not seem to work. I am using the google installer but I get this error with any go build:

Unpacking Go from https://storage.googleapis.com/golang/go1.5.3.linux-amd64.tar.gz to /var/lib/jenkins/tools/org.jenkinsci.plugins.golang.GolangInstallation/Go-1.5.3 on Jenkins
[workspace] $ bash /var/lib/jenkins/jobs/hugo/workspace/hudson.20160219181201.184.sh
$ go get github.com/stretchr/testify
/var/lib/jenkins/jobs/hugo/workspace/hudson.20160219181201.184.sh: line 15: go: command not found
ERROR: (Java::Hudson::AbortException)

Are there any prerequisites, anything that must be done on the system to get it working?
Thanks for your attention.
