Missing functions/arptc_first_chain in arptables source code

Hi, 
  I am trying to use arptables on one embedded platform. After downloading the
source code and cross-compiled it, execute, it generates the following error:

# ./arptables
modprobe: cannot parse modules.dep
arptables v0.0.3-3: can't initialize arptables table `filter': arptables who?
(do you need to insmod?)
Perhaps arptables or your kernel needs to be upgraded.

Checked source code, a lot of functions are missing, for example,
arptc_first_chain. Is there any other packages I need to download?

Thanks, 

Roy
