For some reason, the object you are using does not have makepy support, 
which is unusual.

Generally, you can do a QueryInterface for the object.  However, if the 
object does not support IDispatch, you will haver trouble - we don't 
support arbitrary interfaces when calling them, only implementing them.


ob = ob._obj_.QueryInterface(

The GUID must be for a type library.  If you run "makepy.py -i", then 
you will get a list of all valid typelibs you can use, and the params 
for it.
