[Zope] Cannot redistribute ZClass product

[pieter claassen]

For some reason, I packed my ZClass product and installed it on a new
machine. I thought I gave myself the permissions to modify and further
redistribute the product, but alas, when I tried to pack it again on my
new machine, it told me that I didn't have permission to redistribute
the product.

1. Did I screw the packing up or does this happen normally?
2. How do I hack my product to be able to edit and pack it again for
distribution?

Thanks,
Pieter
