[Zope] ChannelTag and Zope 2.4

[Gitte Wange]

Hello

Now that I have upgraded my Zope server I thought that I could use the 
ChannelTag product.
But I get this error when starting Zope:
2001-08-31T09:21:32 ERROR(200) Zope Could not import Products.ChannelTag
Traceback (innermost last):

ImportError: cannot import name saxlib

Anyone who knows what saxlib is and how to solve this ??
