[Zope] Localizer problem.

Hi, I have a little problem with Localizer, I'm using latest stable Zope release based on python 2.1. When I'm adding Localizer object it gives me this: Site Error An error was encountered while publishing this resource. Error Type: AttributeError Error Value: 'module' object has no attribute '_requests' I have itools installed and working, does anybody know what's happening. -- Mike
