You are trying to build against the glibc-kernelheaders. Kernel modules
must be built against the source for the kernel version you are running.

The correct way is to use /lib/modules/$(uname -r)/build

Try this and then try to build the module again. It may cure this
message. 

cd /usr/src/linux-<kernelversion>

make mrproper 

Copy the default Red Hat kernel config that was used to compile the
kernel you have installed. You can look in the "configs" directory of
your kernel source for a listing of the configs available.

Example, this shows I have the uni-processor althon kernel installed.

cat /var/log/rpmpkgs | grep kernel-2.4.18-18.8.0
kernel-2.4.18-18.8.0.athlon.rpm

cp configs/kernel-2.4.18-athlon.config .config


Open the toplevel Makefile in a text editor. Using the above example
this would be /usr/src/linux-2.4.18-17.8.0/Makefile 
Look at the first four lines in the Makefile. 

VERSION = 2 
PATCHLEVEL = 4 
SUBLEVEL = 18 
EXTRAVERSION = -18.8.0custom 

Remove the word "custom" from the end of the EXTRAVERSION line. 

make dep
