You might not really need to recompile the kernel, you might only need to get the kernel-devel (yum install kernel-devel).  Dazuko is a module that gets loaded by the kernel and need not be built-into the kernel.
You should make sure that the kernel-devel in /usr/src/kernels/ is the same version that is returned using uname -r.

If you aren't running a kernel you compiled from source then, yes, you probably will need to compile just this once. As posters have pointed out, dazuko builds as a kernel module, so would only need to build the module (bet see 2.6 below).
If you have 2.6 kernel and SMP, see README.linux26 in the source obtained from http://freshmeat.net/redir/dazuko/45452/url_tgz/dazuko-2.3.3.tar.gz
For some background on dazuko, see http://lwn.net/Articles/206075/
As for building a kernel, I'm out of time right now nut will try to rummage through my previous answers this evening

Dear all
Thak you for your fast response
First , oklit
i followed the article step by step , but the same problem , when i tried to install Dazuko i faced this error :
=====================
discovered host system... Linux (2.6.18)
checking if security module support is enabled... yes
verifying capabilities are not built-in... built-in :(
error: capabilities are built-in to the kernel:
       you will need to recompile a kernel with capabilities
       as a kernel module
=====================
Second , arnold
the package kernel-devel is installed as you see :
=====================
root@cl-t170-130cl [~/dazuko-2.3.4]# rpm -qa | grep kernel
kernel-2.6.18-92.el5
kernel-devel-2.6.18-92.el5
kernel-devel-2.6.18-92.1.22.el5
kernel-2.6.18-92.1.22.el5
kernel-headers-2.6.18-92.1.22.el5
=====================
but  the directory usr/src/kernels dont contain kernel-devel as you see :
=====================
root@cl-t170-130cl [/usr/src/kernels]# ls -l
total 28
drwxr-xr-x  4 root root 4096 Feb  2 19:44 ./
drwxr-xr-x  4 root root 4096 Feb  5 17:36 ../
drwxr-xr-x 18 root root 4096 Feb  2 19:45 2.6.18-92.1.22.el5-i686/
drwxr-xr-x 18 root root 4096 Feb  2 19:25 2.6.18-92.el5-i686/
=====================
and the same problem when i try to install dazuko i get the error above .
Third , duncan_roe

The source packages are using the uname -r naming convention.
The 2.6.18-92.el5-i686 is the source folder for the 2.6.18-92.el5-i686 kernel version.

The http://www.dazuko.org/tconf.shtml#CAPABILTIES-BUILTIN explains what the issue is.

Here is a centos set of instruction to compile kernel.
http://www.howtoforge.com/kernel_compilation_centos

Alternatively, you could try using an alternate anti-virus application such as clamav.net which should compile and install without the need to recompile the kernel which you will have to do for every kernel update you install.
