The automatic font substitution did not work and the resulting file came up
blank. I tried the exact same command on a debian system and it came out
perfect, even with ghostscript 9.05, so it's not just a newer version probl=
em.
After enough trial and error I ended up copying the file
"/usr/share/ghostscript/9.22/Resource/Init/pdf_font.ps" from another system
over "/usr/local/share/ghostscript/9.16/Resource/Init/pdf_font.ps", and it
worked as expected. I believe the ghostscript package should either be upgr=
aded
to the 9.22 release, or at least replace the "pdf_font.ps" file with a newer
version.
