Problem recompiling kernel with iptables v 1.3.2

[vikrant <vikrant@saysnetsoft.com>]

hi

I have mailed my problem earlier but nobody replied so i am sending it 
again hoping some response this time.

I trying to configure iptables with kernel but because of some problem i
am not able to do so.
Some information that i want to give are:-
Operating system - Cent OS4                  #My  operating system on
which i am trying to do
Current kernel version-  2.6.9-11.EL         #Result after running "uname
-r" command
Current iptables version - iptables v1.3.2   #Result after running
"iptables -V" command
-------------------------------------------------------------------
I have used the following command
--------------------------------------------------------------------
cd /usr/src/kernels
ls
2.6.9-11.EL-hugemem-i686       2.6.9-11.EL-smp-i686
2.6.9-11.EL-i686            2.6.9-5.0.3.EL-i686
cd ..
wget  http://iptables.org/downloads.html#iptables-1.3.2
bzip2 -cd iptables-1.3.2.tar.bz2 | tar xvf -
cd iptables-1.3.2/
make KERNEL_DIR=/usr/src/kernels/2.6.9-11.EL-i686/

#Problem occured after running this command
