@Fryguy Correction. To allow the spec to run on a system where python-bugzilla is not installed, the new spec should be:

    it "when the bugzilla command is found and Already Logged in" do
      ignore_warnings do
        RubyBugzilla::COOKIES_FILE = '/'
        RubyBugzilla::CMD = `which echo`.chomp
      end
      cmd, output = RubyBugzilla.login!("calvin", "hobbes")
      output.should == "Already Logged In"
    end
