Scapy install issues. Nothing seems to actually be installed?

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 python gnuplot wrapper . Won't be able to plot.
INFO: Can't import PyX. Won't be able to use psdump() or pdfdump().
ERROR: Unable to import pcap module: No module named pcap/No module named pcapy

Follow these instructions from scapy website. There are dependencies that you must resolve before doing the install. It worked like a charm for me on a Windows machine.

I have collected all the libraries needed for network programming in Python for Windows and made a single integrated installer. Its on Google Code. Just extract and run the installer after reading the installation file, installs all the dependencies needed for running Scapy on Py2.6.

I've also had lots of issues getting Scapy and its dependencies properly installed on my Mac, finally I found Homebrew Python GitHub page https://github.com/Homebrew/homebrew-python it contains lots of helpful/useful brew formula including one for Scapy that worked like a charm for me.

brew tap Homebrew/python
brew install scapy

I also had an issue with my pcapy which was solved by another formula in the repo for pypcap, so same procedure.

brew install pypcap

Install libdnet:http://libdnet.sourceforge.net/ and python-libpcat: http://sourceforge.net/projects/pylibpcap/

For libdent:

CFLAGS='-arch i386 -arch x86_64' ./configure --prefix=/usr
archargs='-arch i386 -arch x86_64' make
sudo make install
cd python
sudo python setup.py install
