I'm fully aware of the problem you're talking about. However, it  
isn't what I'm describing.

In any of the circumstances you mention, the *distribution* won't  
include the package data. In my case, it's the installed *egg* that  
doesn't include package data. The distribution (created with sdist)  
is actually fine, it does include the package data. setuptools just  
doesn't install it into the egg.

For example, download and unzip http://pypi.python.org/packages/ 
You will see it includes all of the extra data files. But when you do

   easy_install zope.app.securitypolicy-3.4.0.zip

(best done in a virtual-python or virtualenv), you'll find that the  
installed egg does not have any of the ZCML files.
