The tools are *local* utilities. Including the ZCML doesn't fix this 
issue. You have to run the upgrade step.

It should be possible to use the ZMI without this kind of errors. In 
some places I added fallbacks like this one:

         try:
             utool = getUtility(IURLTool)
         except ComponentLookupError:
             # BBB: fallback for CMF 2.2 instances
             utool = aq_get(self, 'portal_url')

If you can't run the upgrades from the ZMI it might be necessary to add 
more fallbacks in CMF.


HTH,
