[CentOS] Error occurs when build kernel 3.2.0

Hi all,

Please let me know if this is not the right place to ask this question.

I was trying to compile and build kernel 3.2.0, by following <Linux 
Administration - A Beginner's Guide> written by Wale Soyinka.

Error occurs after running the following command:

    # new-kernel-pkg -v --mkinitrd --depmod --install 3.2.0-custom
    initrdfile is /boot/initrd-3.2.0-custom.img
    running depmod for 3.2.0-custom
    creating initrd: /sbin/mkinitrd --allow-missing -f
    /boot/initrd-3.2.0-custom.img 3.2.0-custom
    found /boot/initrd-3.2.0-custom.img and using it with grubby
    adding 3.2.0-custom to /boot/grub/grub.conf
    /etc/lilo.conf does not exist, not running grubby

Does anyone ever run into this? How can I fix it?

Here is the link that I downloaded kernel from:
http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.2.tar.bz2

    # uname -a
    Linux test_server 2.6.32-431.11.2.el6.x86_64 #1 SMP Tue Mar 25
    19:59:55 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

    # cat /etc/redhat-release
    CentOS release 6.5 (Final)

Please let me know if any other information is needed.

Thanks.
