I'm working up a patch right now for juju core (master-only).  Some of
our other dependencies will need to be updated to use the new
locations:

gopkg.in/macaroon-bakery.v0
    code.google.com/p/go.net -> golang.org/x/net
bitbucket.org/kardianos/service
    code.google.com/p/winsvc -> ???

Also, the GCE provider relies on code.google.com/p/goauth2 which is
deprecated and the replacement is not compatible, so I'll post a
separate patch to address that for 1.23 and master.
