Comment 3 for bug 1388477

I confirm that adding the namespace declaration fixes things in a number of cases. For instance this one:

virtualenv sandbox
source sandbox/bin/activate
pip install anybox.paster.odoo
pip install anybox.recipe.openerp
pip
Traceback (most recent call last):
  (...)
  File "<string>", line 1, in <module>
KeyError: 'anybox'

I believe it won't hurt to add the declaration and can also help with the other issue in this bug.
Reopening until we see if we can reproduce or not after 1.8.6
