since the move to cairo/pango all the magic of generating output is
taken up by cairo/pango, so the best bet is to make sure you use
the latest versions of these two libraries ...

on the rrdtool website you can find instructions on how to install
a private copy of these so that you do not have to mess with the
base install of your box ...
