[SOLVED] Compiling Opencaster from source

[SOLVED]:

Change the 15th line of "mpe.c" (Under 'tools/mpe2sec') from
#include <net/if_tun.h>
Fixed:
#include <linux/if_tun.h>
Fix courtesy tomk.

So, I am encountering this odd little error when trying to 'make' Opencaster (Source Code) from source. On previous installs of Arch, this worked without a hitch. Now however, it shows the following:

mpe.c:15:24: fatal error: net/if_tun.h: No such file or directory
 #include <net/if_tun.h>
                        ^

Here is the entire trace:

mpe.c:15:24: fatal error: net/if_tun.h: No such file or directory
 #include <net/if_tun.h>
                        ^
compilation terminated.
Makefile:11: recipe for target 'mpe.o' failed
make[2]: *** [mpe.o] Error 1
make[2]: Leaving directory '/home/ushio/cide/oc/opencaster-3.2.2/tools/mpe2sec'
Makefile:17: recipe for target 'mpe2sec' failed
make[1]: *** [mpe2sec] Error 2
make[1]: Leaving directory '/home/ushio/cide/oc/opencaster-3.2.2/tools'
Makefile:5: recipe for target 'tools' failed
make: *** [tools] Error 2

I don't recall ever having to install foreign libs, nor using any makeflags. Any assistance here would be grand. I need to test a patch by the end of this week. (And no my patch is not in this source) :)
