That's what I get if I try;

>>> from Gadfly import gadfly

Of course, use of regex instead of re is a whole different kettle of fish 
;-) but if anyone has any patches for the gadfly code that will 'upgrade' 
it I'd be a willing beta tester. Bearing in mind that I can't even import 
the module I'm a little nervous hacking the code myself.

And then the modules are loaded into the local namespace and everything is 
hunky dory.

Certainly does, that nailed it. I must have created an __init__.py 
inadvertently by using 'from ... import'. By removing the file I can 
'import gadfly'. Strange error though.

You are a legend. Thanks very much.
