The problem arises when the standalone hashlib module available on PyPI is installed on Python 2.4 ... though "import hashlib" then works, subsequent code that attempts to use the hashlib routines and hmac together run into trouble because the way the 2.4 hmac module calls the hashlib routines is different from the way 2.5 does...so the 2.4-level hmac calls into the 2.5 level hashlib in a way that blows up. So, this sounds like a bug in Django that will affect people running Python 2.4 + standalone hashlib. The sole import of hmac in Django is in that contrib/messages/storage/cookie.py file, which is new in 1.2 so I believe this is a new problem for 1.2. Workarounds for you prior to getting a fix into Django would be to get rid of the standalone hashlib that's apparently installed, or use a more recent level of Python.
