sechecker tool not working

We are trying to run the sechecker tool on one of our boxes based on RHEL6 and get the following error.. [root@vos-cm142 ~]# sechecker -m types_wo_allow -v Using policy: /etc/selinux/targeted/policy/policy.24 Using file contexts: /etc/selinux/targeted/contexts/files/file_contexts ERROR: Cannot get avrules: Neverallow rules requested but not available ERROR: Cannot get avrules: Neverallow rules requested but not available ERROR: Cannot get avrules: Neverallow rules requested but not available ERROR: Cannot get avrules: Neverallow rules requested but not available Is this a known issue.
