ip_wccp is compatible with the RedHat kernel sources, but it is a bit
tricky to build custom modules without building a full custom
kernel..

Build custom RedHat kernel:

   rpm -i kernel-source-2.4.XX-Y.rpm
   cd /usr/src/linux-2.4.XX-Y
   make mrproper
   cp configs/config_matching_your_kernel_type .config
   make oldconfig / make xconfig / make menuconfig
   make dep; make clean;
   make bzImage; make modules
   [take note of the GCC flags shown during "make modules"]

Install newly built kernel

   make modules_install; make install

Boot into the new kernel to verify that it works

Change boot menu to default to the new kernel
   [default=0 in /etc/boot/grub/grub.conf]

Build & install ip_wccp module

   gcc [flags collected above] -o ip_wccp.o ip_wccp.c
   mkdir /lib/modules/2.4.XX-yycustom/net
   cp ip_wccp.o /lib/modules/2.4.XX-yycustom/net/
   depmod -a

Load ip_wccp module and verify WCCP functionality

   modprobe ip_wccp

Set up the sytem to load ip_wccp automatically on system boot

   echo "modprobe ip_wccp" >>/etc/rc.d/rc.local
   [alternatively add the modprobe line to /etc/rc.d/init.d/squid]

Is this the only error you get, or do you get other errors before
this?

What I can think of is if you are not booting with a initrd matching
the same kernel..
