Since Grok uses the egg-based distribution of Zope-3. I don't think we 
could've made it to work with a Zope-3 installation-from-a-tarball.

Grokproject does ask for a shared egg directory. It defaults to 
~/buildout-eggs. I wonder what the reason could be this question was not 
asked when running grokproject. What version of grokproject are you 
using? Could update it with something like "easy_install-2.4 -U 
grokproject"? Does that help?

I understand that. We've been very annoyed too with all the weird and 
unpredicatable version conflicts. We tried to solve that problem and we 
had the impression we nailed it. So thanks for your report, because 
apparently something is not quite right somewhere. I'll have a look..:

Ah, now I think I have found the problem: you're using a very old 
version of grokproject. A version that does not yet now of the better 
way of handling the dependecy versions. As I suggested above, try to 
update grokproject. It should ask you then indeed for a shared eggs 
directory. Mind though, that I suspect you will need to download quite 
some different versions of eggs again... I'm sorry for that.

I hope this helps and that you're still inclined to give Grok a try..!
