Try to activate a gem containing path. Returns true if activation succeeded or wasn’t needed because it was already activated. Returns false if it can’t find the path in a gem.

  def self.try_activate path
    # finds the _latest_ version... regardless of loaded specs and their deps
    # if another gem had a requirement that would mean we shouldn't
    # activate the latest version, then either it would already be activated
    # or if it was ambiguous (and thus unresolved) the code in our custom
    # require will try to activate the more specific version.
