Ah yes, my recommendation was made too quickly.  The last two should  
not have been there.  This third stanza would do the trick.

    <content class=".catalogindex.NormalizationWrapper">
      <require
          permission="zope.ManageServices"
          interface="zope.app.catalog.interfaces.IAttributeIndex
                     zope.index.interfaces.IStatistics"
          set_schema="zope.app.catalog.interfaces.IAttributeIndex"
          />
    </content>

I made this change in svn.

Right, then it needed a declaration for  
BTrees.Length.Length.__call__.  This is in svn now too.

Try getting rid of your changes and getting the new version from  
svn.  It should do what you want.
