[Zope3-dev] ImportError: cannot import name IObjectEvent when I install Zope3 Wiki 0.2.5

[KLEIN Stéphane]

Hi,

I've installed with success Zope 3.2.0 on Ubuntu from source (I haven't 
used Ubuntu Zope Package).

Now, I would like to install Zope3 Wiki 0.2.5 package. I've fetched wiki 
source from SVN. Next, I've put this file in /lib/python/ directory in 
my Zope instance : /var/zope/1/lib/python/zwiki/

Next, I've put zwiki-configure.zcml file in 
/var/zope/1/etc/package-includes/ directory. zwiki-configure.zcml contain :

<include package="zwiki" />

Now, when I restart zope (/var/zope/1/bin/runzope) I've this error :

   File 
"/usr/local/src/Zope-3.2.0/build/lib.linux-i686-2.4/zope/configuration/config.py", 
line 184, in resolve
     mod = __import__(mname, *_import_chickens)
   File "/var/zope/1/lib/python/zwiki/interfaces.py", line 22, in ?
     from zope.component.interfaces import IObjectEvent
zope.configuration.xmlconfig.ZopeXMLConfigurationError: File 
"/var/zope/1/etc/site.zcml", line 7.2-7.55
     ZopeXMLConfigurationError: File 
"/var/zope/1/etc/package-includes/zwiki-configure.zcml", line 1.0-1.27
     ZopeXMLConfigurationError: File 
"/var/zope/1/lib/python/zwiki/configure.zcml", line 84.2-87.8
     ImportError: cannot import name IObjectEvent

Full log in file joined.

Thanks for your help,
