I think the problem is coming from the fact that both logilab-common and
logilab-astng are in the logilab package, and while looking for logilab.astng,
python found hte logilab package in the logilab-common egg, don't find astng 
here and then stop with an ImportError. IIRC this is the reason why we don't 
support eggs/easy_install at this time.
