I agree but where do you raise the exception?  Quite frankly it's
silly to kill the whole app when a bunch of debug lines won't print
and shouldn't except by the developer..
In other words is what you propose the right way to solve this for
modules which were'nt included in older python releases?  Or should I
be doing something different and if so what should I do?  I like the
solution you give - it will work for everything I do - but is it smart
to retrofit this into all of my old code?  What is the clean way to
solve this?

Just want to do this the right way.
