[Zope] Installing the Managment product for RSS Channels

[Gitte Wange]

Hello,

I have tried to install the RSS Channels product found at:
http://www.zope.org/Members/TheJester/ChannelTag

I seems very useful. (I want to add Slashdot news to my portal *S*S*S*)

Well .. there's only one problem. The product won't go into Zope :-(

I have untared the tarball into the Products directory.
When I try to restart Zope it tells me that I need a xmlsax module.

Hmm .. where do I find this module ?

I have tried a search on the zope.org site but found nothing.

Anyone else using this product ?

Regards,
Gitte Wange
