zipextimporter, as published, doesn't handle extensions in packages.
The patch I attached at the end, may fix this - I tested it with PIL.
It may work with zope, or may not - depends on how the extensions are
structured. If there are extensions/pyds that link to other
extensions/pyds, then it will most certainly not work.
If it doesn't work, you could still try the py2exe approach:
py2exe bundles the .py modules in a zip file, and also inserts loaders
for extensions into the zip file. The loaders load the .pyd extensions
from the file system.
