[rrd-users] rrdtool perl interface from 1.0 to 1.2

[Tobias Oetiker]

Xavier,

note that 1.2 is able to read ad write  ALL 1.0 rrds the problem
may be that the old server was 32bit while the new one is 64 bit
... curently this is not compatible since the rrdtool data format
is architecture dependant ...

cheers
