I don't actually see that here, if matplotlib is installed it looks
like this:
$ scapy
INFO: Can't import PyX. Won't be able to use psdump() or pdfdump().
WARNING: can't import layer tls: No module named _MD2
Welcome to Scapy (unknown.version)
And if it isn't installed:
$ scapy
Traceback (most recent call last):
File "/usr/local/bin/scapy", line 25, in <module>
interact()
File "/usr/local/lib/python2.7/site-packages/scapy/main.py", line 300, in
interact
scapy_builtins = __import__("all",globals(),locals(),".").__dict__
File "/usr/local/lib/python2.7/site-packages/scapy/all.py", line 16, in
<module>
from scapy.arch import *
File "/usr/local/lib/python2.7/site-packages/scapy/arch/__init__.py", line

from matplotlib import get_backend as matplotlib_get_backend
ImportError: No module named matplotlib
