Those scripts where already broken with Python 1.5.1, which was the
first version that deprecated the rand module. It was *not* renamed to
random, the random module was available since 1.0.2. So people had
four years to move from rand to random, and you still can import rand
if you want to in Python 2.2 - if you add lib-old to sys.path.
