run uname -a to determine what version of the linux kernel you're running. You need the same kernel headers as your running kernel. If you compiled your own kernel, point the thing your compiling at that. You don't need to find it as an rpm, you can grab kernel source from ftp.us.kernel.org and extract it to /usr/src/linux (clean up symlinks, extract, create new symlinks) or extract it to your home directory (or where ever it won't overwrite soemthing). Is there a standard enviorment varible for specifing where your kernel sources are? KERNER_DIR or something? Andrew S.
