[Zope] ZInformixDA on Zope2.7.3 problem

Hi ! I'm trying to install ZInformixDA on Zope2.7.3, but it needs a package named informixdb-1.3, and when I execute ./configure it returns a mistake I have python2.3 installed, but I've seen that this package works with python1.5 It's possible that it is an obsolete package? I want to connect Zope2.7.3 under a Knoppix3.7 to a Informix Database with the informix database adapter, and I have this tar.gz: ZInformixDA-0.2.tar.gz.tgz and informixdb-1.3.tar.gz Can you help me? Thanks, Nico
