+***WARNING:*** You do not have the full kernel sources installed.
+This does not prevent you from building the v4l-dvb tree if you have the 
+kernel headers, but the full kernel source is required in order to use 
+make menuconfig / xconfig / qconfig.
+
+If you are experiencing problems building the v4l-dvb tree, please try 
+building against a vanilla kernel before reporting a bug.
+
+Vanilla kernels are available at http://kernel.org.
+On most distros, this will compile a newly downloaded kernel:
+
+cp /boot/config-`uname -r` <your kernel dir>/.config
+cd <your kernel dir>
+make all modules_install install
+
+Please see your distro's web site for instructions to build a new kernel.
