[Zope] TextIndexNG3 fails

[Milos Prudek]

I installed TextIndexNG3 into Zope 2.11.2. When I create a new ZCatalog and in 
the Indexes tab I try to create a TextIndexNG3 index, I get this traceback:

2009-01-28 16:01:32 ERROR Zope.SiteErrorLog

ComponentLookupError: (<InterfaceClass zope.component.interfaces.IFactory>,

What does it mean?
