The path "/usr/src/linux-2.6.22.13-0.3/include" is a kernel header file 
directory, but it does not contain the file "linux/version.h" as expected.  This
can happen if the kernel has never been built, or if you have invoked the "make 
mrproper" command in your kernel directory.  In any case, you may want to 
rebuild your kernel.

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