iptables and FTOS syntax error

Hello,

I have a bizarre problem with iptables when I'm trying to use FTOS:

First, the following works fine using MARK:

iptables -j MARK -A POSTROUTING -t mangle -p udp --dport 123 --set-mark 4

But this one doesn't:

iptables -j FTOS -A POSTROUTING -t mangle -p udp --dport 123 --set-ftos 4

And gives the error message:

iptables: No chain/target/match by that name

A "iptables -j FTOS --help" shows that the FTOS extension was compiled in so 
I'm very confused about the error message.

-------------snip-----------&<----------------
FTOS target options
  --set-ftos value              Set TOS field in packet header to value
                                This value can be in decimal (ex: 32)
                        or in hex (ex: 0x20)

Any help greatly appreciated,

Thomas
