Dear Ladies and Gentlemen,
I have only recently noticed that 2.1.90 fails to initialise the rrd
plugin wiht a dev version of rrdtool (last September CVS checkout I
think: v 1.1.0).
Furthermore this has been the case since 2.1.55.
There are no problems with a stable rrdtool (1.0.40).
I have submitted make census-ok with the config/build details; configure
identifies the rrd libraries and headers.
The error message is

The dev branch of rrdtool has the Holt-Winters prediction CF for
aberration detection (as described in Jake Brutlags wonderful paper).
That said, the data could be imported from a stable rrd to a dev one for
HW analysis.
Yours sincerely.

'...No man is an island, entire of itself; every man is a piece of the
continent, a part of the main. If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friend's or of thine own were. Any man's death diminishes
me, because I am involved in mankind; and therefore never send to know
for whom the bell tolls; it tolls for thee...'
