[rrd-users] can't update 'dummy'?

I'm running RRD 1.0.0 on AIX 4.3.2 with Cricket .69

Cricket's collector code calls:

RRDs::update($datafile, join(":", $when, @data2));

and gets the error:

Cannot update
rrdopen can't open 'dummy'

It's the "can't open 'dummy'" that is confusing me and preventing
things from working properly.   

If I print out the variables passed to RRDs::update, I get:

$datafile =

@data2=1 1 28 36 3941364 10448088

These values all seem correct. Actually, I'm not quite sure what
the $when is doing, but ....

So, why is rrdupdate complaining about "dummy"?  Any ideas, please?
