[mrtg] lastupdate parameter to rrdtool

Somewhere along the line rrdtool had a lastupdate parameter. I was
using that to grab the last set of numbers retrieved for the number of
messages in the queues of a Barracuda spam filter. Lastupdate seems to
have disappeared between 1.2.27 and 1.2.28 and last only returns the
timestamp of the last query.
I am not a programmer in any real sense of the word. I use perl alot,
I was doing:
rrdtool lastupdate <pointer to Barracuda queue size rrd db> > test.txt
I was then parsing test.txt. Is there a way to do that now? I tried to
read Tobi's man pages and am completely lost there.
I was able to figure out how to grab that info from the web interface
from the Barracuda, but that is subject to change(and has recently), so
I would rather get it from the rrd database as snmp seems to be a more
stable source and less likely for Barracuda to change in the future.
