After doing s/rrdool/rrdtool/ :
 979506420:        NaN
 979506480: 4.9955000000e+04
 979506540: 4.9955000000e+04
 979506600: 4.9955000000e+04
 979506660:        NaN

So: please try again.  Just use cut and paste. Make sure to do this in
a directory without a file called x.rrd
rrdtool create x.rrd -b 979506420 -s 60 DS:x:GAUGE:120:0:U RRA:LAST:0.5:1:10080
rrdtool update x.rrd 979506480:49955
rrdtool update x.rrd 979506540:49955
rrdtool update x.rrd 979506600:49955
rrdtool fetch x.rrd -s 979506420 -e 979506660 LAST

If it doesn't produce the correct numbers, retry with a recent version
of RRDtool.

cheers
