Module 'uuid' is used in the Samba 4 Python scripts (e.g. scripting/python/samba/provision.py). This module is new in Python 2.5. Therefore configure should check for minimum Python version 2.5 and fail if an older Python installation is found.
Sorry, I had overlooked scripting/python/uuidmodule.c which seems to implement a wrapper module 'uuid'. Hmm, this is a name clash with module 'uuid' in Python's standard lib which could lead to problems.
I think it does it appropriately right here. I'm using python 2.4 and the wrapper works fine for me. So I don't see any problems here. Closing it with INVALID (at least for now - when we don't suffer other problems).
