Suggesting this diff from v4:

+	# hack when running ima_keys.sh locally from ima_keys.sh directory
+	# LTPROOT=$PWD PATH="../../../../../lib/:.:$PATH" ./ima_keys.sh
+	if [ ! -f "$cert_file" ]; then
+		cert_file="$LTPROOT/../datafiles/ima_keys/x509_ima.der"
+	fi

Not sure if you still doing review & testing, thus waiting for your comments
or tags.
