iptables errors:something wrong with distribution?

[Tyler Littlefield]

Hello list,
I've got a quick question.
I initialize all my rules  to default of drop in my iptables script, which runs every time the computer boots.
Now, I just added a new rule and ran my script again, and I'm getting the following message:
iptables v1.4.1.1: Couldn't load target `drop':/lib/xtables/libipt_drop.so: cannot open shared object file: No such file or director
y
Try `iptables -h' or 'iptables --help' for more information. 
So I may clear up some confusion, drop is capitalized in my script, which reads like this:
<snip>
echo iptables 
echo configuring:
echo -=-=-=-=-=-=-=
echo flushing default rules
iptables -F INPUT 
iptables -F FORWARD 
iptables -F OUTPUT 
iptables -F -t nat
echo setting default policies
iptables -P INPUT DROP
iptables -P FORWARD DROP
iptables -P OUTPUT ACCEPT 
</snip>

Thanks,
Tyler Littlefield
