[Grok-dev] Re: Upgrade problem "type object 'IRole' has no attribute '__iro__'"

[Sebastian Ware]

Added

   zope.app.session

to

   install_requires

more success, but now it looks as though the grok.container is having  
problems. Any other versions to pin down? Or is it possible to just  
upgrade all the objects? :)
