[rrd-users] ERROR: unknown function 'VDEF'

I am using rrdtool-1.0.33 and I would like to create the following graph:

rrdtool graph percent.gif \
--start 1011060000   \
--end 1011192020 \
DEF:ds=data.rrd:n:AVERAGE \
VDEF:first=ds,FIRST \
VDEF:last=ds,LAST \
VDEF:pct=ds,95,PERCENT \
VRULE:first#FF0000:"start of data" \
VRULE:last#FF0000:"end of data" \
HRULE:pct#FF0000:"95th percentile" \
GPRINT:pct:"%6.2lf Bps\n"

I get an error message :  ERROR: unknown function 'VDEF'

I have read in the rrd-developers list from the 25 Jul 2001 01:57:40  that
the percentile function has been added.
My question now. Do I have to install some additional patches?
It looks like my version doesn't understand this feature yet.

Any help would be apreciated. Thanks
