Error when launching scapy

[emx]

I have just downloaded the latest scapy and here is what I get:

[root@vasapp7 ~]# ./scapy.py -s mysession
  File "./scapy.py", line 604
    xx = sum(len(k) for k in linex)
                      ^
SyntaxError: invalid syntax

Here is my python version:

[root@vasapp7 ~]# python -V
Python 2.3.4

And my OS environment:

[root@vasapp7 ~]# uname -a
Linux vasapp7 2.6.9-55.ELsmp #1 SMP Fri Apr 20 16:36:54 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux

Scapy needs python 2.4 since a long time now.
