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().

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.
http://www.secdev.org/projects/scapy/doc/installation.html#mac-os-x
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
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.
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
I was able to get this working by #commenting out the route6 import statment in all.py within the scapy mod directory.
After that, I was able to bring up the interactive scapy prompt.
So the real solution to this issue is to make sure you have a compatible route6 mod.
MAC install follow the instructions
here in case if you want to install it in a virtualenv by first going into the virtualenv and then just using python setup.py install instead of sudo.
