The header files in /usr/include are generally for C libraries, not for the 
running kernel. If you do not have kernel header files in your /usr/src 
directory, you probably do not have the kernel-source package installed. Are you
sure that /usr/include contains the header files associated with your running 
kernel? [no] 

What is the location of the directory of C header files that match your running 
kernel? [/usr/src/linux/include]
