Dump file not defined (sorry for the repeat!)

Hello

I have a similar problem to a posting about 8 months ago. Basically pizza.py isn't recognising the command dump.

I am currently using python 2.7 and all relevant packages required have been installed (Tk, Numeric, Tcl etc). The version of pizza.py I am using is 24Nov10.

here is the output I have from running python, then pizza.py, then trying to use the d = dump() function:

Traceback (most recent call last):
File "", line 1, in
NameError: name 'dump' is not defined

The 'No protocol specified' worries me and makes me wonder if this is something to do with the problem.

Any ideas anyone?

Thanks alot :)

Jay
