Scapy throwing syntax error for python 2.6.6 application

I had worked on a program in Python2.7 and need to retool it for Python 2.6.6. I made some minor changes but receive this error when trying to compile. Has anyone ran into this before? I couldn't find very much on Google. Any help would be appreciated

 Traceback (most recent call last):
  File "makexml.py", line 13, in <module>
    from scapy.all import rdpcap
  File "/user/.pyenv/versions/2.6.6/lib/python2.6/site- 
  packages/scapy/all.py", line 11, in <module>
    from scapy.config import *
  File "/user/.pyenv/versions/2.6.6/lib/python2.6/site- 
packages/scapy/config.py", line 84
    self.layers = {owner for f in self.fields for owner in f.owners}
                           ^
   SyntaxError: invalid syntax

Scapy 2.4.0 is not compatible with Python 2.6. You should downgrade Scapy to 2.3.3, which has Python 2.6 (and 2.5, I think) support.

Set comprehensions are a new feature from Python 3 that got backported to Python 2.7.

So if you try to use one in an earlier version, you get a SyntaxError.

The simplest change is to pass a generator expression to the set constructor:

self.layers = set(owner for f in self.fields for owner in f.owners)

(This will work all the way back to 2.4. Before that, there's no builtin set, and no generator expressions, but you'd probably have bigger problems with, e.g., exceptions…)
