firestarter dhcp and KDE 3.2.0

[Sparkfish]

Just installed firestarter-0.9.2-r1 and it wont start keeps giving the error that

"No DHCP Client found" in a popup

at the end of the wizard.
Now i know dhcp is working because i am uaing it now also
having looked in /etc/firestarter/firewall.sh
i know it is picking up my local ip from the router by extracting the the code

#!/bin/sh

IFC=/sbin/ifconfig

IF=eth0
IP=`$IFC $IF | grep inet | cut -d : -f 2 | cut -d \ -f 1`
MASK=`$IFC $IF | grep Mas | cut -d : -f 4`
NET=$IP/$MASK

echo $IP
echo $MASK
echo $NET

Can anyone shed any light on this for me. Cheers in advance.
