How do I build an rpm from source files rather than src.rpm file assume files have are located in the /usr/src/redhat/SOURCES directory and the spec file is located in /usr/src/redhat/SPECS

By the way the files are the kernel source for kernel version 2.6.9-1.667. Building the kernel from the kernel-2.6.9-1.667.src.rpm does not help me.

Why does it not help you? Can you elaborate?

The reason it doesn't help me is when I build the rpm from the src.rpm it does not give me the source files for the kernel. The installation puts the compiled kernel modules in /lib/modules/2.6.9-1.667.root
There is a symlink to the source but when I looked in the source directory for the source code there were no souce files, only Makefiles and in some cases Kconfig files. I need to change one setting in the .config file. Since there are no source files I can't recompile the kernel. The only way I was able to get the kernel source on my computer was to install the src.rpm and then untar the kernel source and put it in the /usr/src directory. However when I did that the patches that redhat implemented were not appled to the kernel and the kernel would not compile completely.

The rpm you are looking for is called "kernel-sources.2.x.x.rpm".
