That example is meant to be run from the POX CLI/interpreter (that is, it
expects you ran the "py" component), not as a standalone component.
You could turn it into a component with a little work (it has already been
discussed on the mailing list). However, there's a "Statistics Collector
Example" in the "Third Party" section of the manual wiki which has already done
this (and expanded on the original a bit).
Hope that helps.
