  I even use the newest version of zope.component.

   I don't recommend autoinclude; since you should not include the
meta.zcml of grokcore.view in Zope 2 (unless you want some bugs). It's
the responsability of each package to say which extension it depends on
and which configuration to load. If you want to automatically include
configuration files, do it only on the top level one, not the
dependencies (I don't known if autoinclude do that).


   I recommand in your extension to add a:

  <include package="five.grok" file="meta.zcml" />
  <include package="five.grok" />

  Best regards,

  Sylvain,
