ditto here -- it is good to have an authoritative translation in the

I've peeked at the changes in gs pdf font handling -- there are major
differences between 8.60 and 8.14 versions of pdf_fonts.ps
and pdf_main.ps.  The current version will only issue one warning
for each undefined procedure, but I still don't know why gs ever thought
the test file had undefined procedures.  Pdf font handing is quite a bit
different from the underlying postscript, so it is not surprising that
.ps works where .pdf fails.  Consider the target audience for desktop
linux -- e.g.,
refugees fleeing from Win32, where pdf is not widely used.  Most linux
distros use ESP gs 8.14 or 8.15 to support printing .ps files to non-ps
printers.  For rendering .pdf files reliably a more recent gs, apparition,
xpdf, etc. are probably more reliable.
