We don't need a --assert.

if [ ! -x /usr/bin/dpkg-log ]; then 
	eval 'dpkg-log () {
		while expr "$1" : "-"; do
			shift
		done
		echo $*;
	}'
fi

And if that is too much verbiage, all that is needed is a depends on
whatever package provides dpkg-log. --assert is not intended for this
kind of thing.
