 From /usr/src/UPDATING:

20030925:
Configuring a system to use IPFILTER now requires that PFIL_HOOKS also 
be explicitly configured.  Previously this dependency was magically 
handled through some cruft in net/pfil.h; but that has been removed. 
Building a kernel with IPFILTER but not PFIL_HOOKS will fail with obtuse 
errors in ip_fil.c.

Regards, Matt.
