Steven, I think you're wrong with regard to the error message. 
Straight from the tarball, Python-2.7.2/Lib/hashlib.py line 135ff:

for __func_name in __always_supported:
    # try them all, some may not work due to the OpenSSL
    # version not supporting that algorithm.
    try:
        globals()[__func_name] = __get_hash(__func_name)
    except ValueError:
        import logging
        logging.exception('code for hash %s was not found.', __func_name)

Of course this does not invalidate the fact (is that even possible?) of
the brokenness of the installation.
