sebek compile trouble

[Tom <tomd2004 () gmail com>]

Hi,
I'm having trouble compiling sebek-lin26-3.1.2b on a vanilla 2.6.16.16 kernel.
I'm using libnet-1.1.2.1 which is installed in /usr/include/

the output of the configure script is:

checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for gcc... gcc
checking for C compiler default output file name... a.out
checking whether the C compiler works... yes

checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes

And make 2> is:

/tmp/sebek-lin26-3.1.2b/src/sebek.c: In function `parse_params':
/tmp/sebek-lin26-3.1.2b/src/sebek.c:168: error: `ARPHRD_ETHER'

make[1]: *** [_module_/tmp/sebek-lin26-3.1.2b/src] Error 2
make: *** [sebek] Error 2

Any suggestions would be really appreciated.

Thanks,
