Not sure if puppet has something similar but in cfengine I could do this:
[root@us-cfe002:~]# cfagent -v -q -n 2>&1 | grep -i need
Need: Update of image /var/cfengine/inputs/common/openmq_base.conf from
master /nfs/exnas/root/cfengine/configs/common/openmq_base.conf on localhost

Of course you could make a little bigger script to send something
more descriptive in the email.

I think red hat satellite server can do this(I think, it uses an
Oracle DB to store data so you could query that), I think they released
an open source version of it -
http://www.redhat.com/spacewalk/
I have not used either personally.
