Specific bug reports are nice. :)

>From a quick look&test, it seems to be just a matter of fonts. .gmodels
contain hard-coded font names ("Helvetica" and "Helvetica-Bold", in this
case), and most back-art installations don't have these. This can't be
fixed properly (flaw in the format; it'd have to be changed to handle
this correctly), but it seems that the gmodel code shouldn't just fail
if the decoding system doesn't have the exact same font.

Thus, I've attached a patch that makes the gmodel loading code fall back
to the system font if no font with the given name exists. Could someone
more familiar with the gmodel loading check if this is a sane approach
for gmodels?

With this patch, Cenon starts and opens the examples I tested ok. :)
