Hi all,
I would like to continue this discussion:
http://lists.plone.org/pipermail/plone-product-developers/2011-January/009956.html
cause I'm facing a similar issue. I've made some debug about that and I
think that this is a bug in z3c.autoinclude. This is the process of
z3c.autoinclude that generates this error:
1. z3c.autoinclude lists your product's dependencies (ref:
z3c.autoinclude.dependency.py#L24)
2. for every dependency, it checks if exists a file
namespace_packages.txt in its egg-info dir (ref:
z3c.autoinclude.utils.py#L123)
3. if that file doesn't exists , it searches for other packages in the
same path of the dependency (why?! this doesn't make sense and it's
dangerous if that product is anywhere in the python path) (ref:
z3c.autoinclude.utils.py#L26)
4. the fact that the final error is "ImportError: No module named PIL-1"
is simply because the PIL package has a file __init__.py in its root
directory but it could be any other package. (ref:
z3c.autoinclude.utils.py#L61)
(I've omitted some jumps for briefness but you can easily follow every
step from the point 1.)
The solution suggested by Ross will probably work but IMHO it's not a
definitive solution. The error in point 3 still remains: any time you
have a dependency in "lib/python2.6/site-packages" you are likely to hit
this issue.
With this simple patch everything works smoothly:

What do you think? Am I wrong?
