It isn't a "sin bin";  TTW-scripting (PythonScripts, and, in 2.4, DTML) have
a "deny by default" access policy for Python modules;  you can "bless" 
the md5
module using a "patch-style" product, as described in the PythonScript 
product's
README ('lib/python/Products/PythonScripts/README.txt').

You can use an ExternalMethod, if you prefer not to go this route.
