What version of policycoreutils?

The implication is that there were no avc denials
in /var/log/audit/audit.log, and thus the generated module was empty.
Possibly your audit logs were automatically rotated?

You should really be using the -a option btw, e.g.
	audit2allow -a -M local
That will pull all messages from audit, including older audit logs I
believe.
