[tproxy] --on-port issues

[Ritter, Nicholas]

I noticed in a search of the list going back that others reported
problems with cttproxy, iptables 1.3, and an error from iptables
concerning the invalid arguement of '--on-port'. I don't recall finding
and resolutions.

I apply the cttproxy patch and the patch applies with no problems,
builds with no problems, but insmod refuses to load the module, and I
suspect that the failure to load the module is why I am getting the
--on-port related errors.

Any thoughts on how to fix this?
