You probably didn't enable CONFIG_PACKET in your kernel, or you
configured it as a module, but didn't add the correct alias in
/etc/modules.conf. From Configure.help :
Packet socket
CONFIG_PACKET
  The Packet protocol is used by applications which communicate
  directly with network devices without an intermediate network
  protocol implemented in the kernel, e.g. tcpdump. If you want them
  to work, choose Y. 

  This driver is also available as a module called af_packet.o ( =
  code which can be inserted in and removed from the running kernel
  whenever you want). If you want to compile it as a module, say M
  here and read Documentation/modules.txt; if you use modprobe or
  kmod, you may also want to add "alias net-pf-17 af_packet" to 
  /etc/modules.conf.
