[Linux] graphics/libv4l compilation error

[Mayuresh <mayuresh%acm.org@localhost>]

This is my first encounter with pkgsrc on Linux.
Trying to compile sane-backends which leads to a dependency on
graphics/libv4l

# uname -a
Linux hp 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1 (2015-05-24) x86_64 GNU/Linux

pkgsrc state: up to date

log.c:28:28: fatal error: linux/videodev.h: No such file or directory
 #include <linux/videodev.h>
                            ^
compilation terminated.


There is a file named that but not under "linux" directory:

# find work -name videodev.h -ls
207341   12 -rw-r--r--   1 root     root        12274 Jul 13 19:55 work/.buildlink/include/videodev.h


Any hints?

Mayuresh.
