building nvidia kernel module

[jbk]

I'm trying to get the nvidia-kmod driver installed on my 
system. I am very close to doing it but I need to change the 
  path of an expected source. I know that some of you are 
involved with building packages for the fedora project so I 
hope this issue is familiar. First I will paste a link to 
the thread on fedoraforum that outlines what I'm trying to 
do and then the output from the command on my system that is 
complaining.

How do I modify or create a environment variable that points 
to the current kernel source for my system.

$ rpmbuild -ba nvidia-kmod.spec --target=`uname -m` --define 
'kvariants ""'
Building target platforms: x86_64
Building for target x86_64
error: Failed build dependencies:
kernel-devel-x86_64 = 2.6.18-1.2849.bag.v1 is needed by 
nvidia-kmod-1.0.8776-1.2.6.18_1.2849.bag.v1.x86_64
I created a link in /usr/src/kernels/ that points to the 
source file of the compiled kernel but it is ignored. The 
expected path must be hard coded in the environment the 
rpmbuild builds from. How do I change this?

If there is more information needed I would be happy to find 
it and post
