After doing a apt-get source iptables,
dpkg-buildpackage -rfakeroot
I get the following output:

.
.
.
dh_install
cp: cannot stat `debian/build/iptables-1.2.7a/ippool/ippool': No such file or 
directory
dh_install: command returned error code
make: *** [binary-arch] Error 1

Anyone know what I should do?
Cheers
Cirrus
