Hey guru's

Just installing Rational ClearCase on a linux box, with kernel version:
# rpm -qa | grep kernel

The Clearcase install is looking to rebuild the kernel, but the source code for the kernel isn't included when the OS was installed.

Would a reinstall be needed, and specify somewhere that include kernel source files, or can I just copy these from the installation media / or somewhere onthe net so I can rebuilt the kernel to the required version for ClearCase
