the problem with the fonts is that your system seems to be missing
a 'fixed width' font. rrdtool 1.3 uses fontconfig to pick up the
fonts. it looks for one of the following fonts.

 DejaVu Sans Mono,Bitstream Vera Sans Mono,monospace,Courier

you can type


to see what you have. I would recommend installing the dejavu fonts
and then running fc-cache and checking with fc-list that they get

maybe it is sufficient to ruun fc-cache

also there is a config file for the whole fontconfig stuff,
probably in /etc/fontconfig
