Hi Steve
Thanks for your help. I do get Python 3.4.0 when I run $VENV/bin/python
I also had all of the requirements followed and I executed all steps in the 
scaffolds.html page. (I used copy/paste so there were no typos etc.
I will take the suggestion of wiping the directory and starting the 
tutorial again.  I will repost here to let you know what happens

Thanks again.
Brian

fyi (in case it turns out to be interesting...).  I had progressed as far 
as tutorial 12  (Templating with Jinja2) when I first noticed the error.  
It is possible the error occurred before this step and I hadn't noticed 
it.  In any event, I went back over previous tutorials, eventually going 
back to the scaffolds tutorial, and the error still came up.  But a clean 
start will be useful, and as I said, I will post the outcome here.   Cheers.
