I have an apple computer running Leopard with python 2.6. I downloaded the latest version of scapy and ran "python setup.py install". All went according to plan. Now, when I try to run it in interactive mode by just typing "scapy", it throws a bunch of errors. What gives!

Just in case, here is the FULL error message..

INFO: Can't import PyX. Won't be able to use psdump() or pdfdump().
