errors in go library installs

[iantor]

On Win 7-64, installed latest Vagrant and Virtualbox (that version is higher than the one you suggest). vagrant up seemed to go well, until the last stage where vagrant libraries are installed. Go seems to have been installed ok, but got the following errors from the provisioning script:
