Because that's the wrong recipe... see


Fake eggs are done on the Zope *install* not on the individual Zope

The real reason is that I was fiddling with the buildout until I could 
make it work. However, for buildouts like this where the whole thing is 
about a single set of eggs (i.e. you want both the instance, the custom 
interpreter and the test runner to work on the exact same working set), 
I find it more natural to declare those at the top and re-use the 
variable throughout. It's just a personal preference, though.

Yeah, I thought so too, but for some reason they weren't - or rather, 
grokcore.security was missing in bin/test. I just wanted to get 
something that worked checked in quickly, but we should try to take it 
out again and work out if/why it fails to pick it up.
