[CentOS] backuppc problem

I've installed backuppc from the EPEL repository.  It does backups just 
fine, BUT, when the backups are done, the status on the web page says 
there are no backups for any of my systems I'm backing up.

To be sure, they are taking up disk space, but it's just not reporting 
it correctly to the admin web interface.

I'm thinking I'm missing some package I need, but am not sure exactly what.

Any ideas?

Thanks.
