The problem is that the program assumes (contrary to the warning on
p. 421 of the Second Edition of the PostScript Language Reference
Manual) that all available fonts appear as entries in FontDirectory.
This is the case for most printers, but it is not part of the
PostScript language definition.  Ghostscript, in particular, loads
all fonts from disk dynamically; they don't appear in FontDirectory
until they've been loaded.

You can work around this problem by invoking
	loadallfonts
before running the program.
