Patch-o-matic says "unable to find ladd slot" in Makefile

[Glen Turner <glen.turner@aarnet.edu.au>]

Hi folks,

I've written a patch for the Linux kernel and for iptables
which adds a TCPCONG netfilter target to set the TCP congestion
control algorithm.  Now I can run a different algorithm for
traffic using the the WLAN interface than for traffic using
the wired interface.  Code at
   <http://www.aarnet.edu.au/~gdt/patch/tcpcong/>

I've tried my best to follow the instructions at
   .../patch-o-matic-ng/README.newpatches
which I think asks that a file
   .../patch-o-matic-ng/patchlets/TCPCONG/linux-2.6/net/ipv4/netfilter/Makefile.ladd
be created containing
   obj-$(CONFIG_IP_NF_TARGET_TCPCONG) += ipt_TCPCONG.o
rather than this being left in the
   .../patch-o-matic-ng/patchlets/TCPCONG/linux-2.6.patch
file.

Unfortunately when I run patch-o-matic
   KERNEL_DIR=~/linux-2.6.18  \
   IPTABLES_DIR=~/iptables-1.3.6  \
   ./runme base
I get this error

Should I have left the change to net/ipv4/netfilter/Makefile
in the file linux-2.6.patch? Or is some other magic required?

Thanks muchly,
Glen
