Hey, Andy,

I poked around a bit before I changed to an older PyX, and (if I'm 
remembering correctly) saw several calls to pyx.deco._arrowhead() 
complaining about not being passes enough arguments.

After I changed PyX versions and found PyFeyn working and nothing else 
broken, I quit looking...

Hope this might be helpful- maybe it's the only thing that needs changing?

Later,
George
