Re: Can anyone point me in the right direction here?

There are a few things that look very dubious on the command line: first
is the "--" - that option is quite obscure, and rarely needed, except in
a few special utility Postscript jobs.

If the "--" *is* required, then there is Postscript involved which we
can't possibly guess at.


Secondly, (possibly related to the "--") the "-c" and "quit" are
superfluous.

Lastly, when trying to diagnose problems, it's really quite daft to
minimise the feedback Ghostscript is giving by using the "-q" option.

What you need to do is get the PDF in question, and run Ghostscript at
the command line (outside of Rails and Docsplit), but using the same
command line. If it doesn't go wrong, then it is likely something in the
Rails environment settings causing it to fail, so I would compare the
environments on the working vs non-working machines.

If it still goes wrong at the "vanilla" command prompt, then it's
possibly an issue with the PDF, an issue with Ghostscript, or an issue
with the overall environment (not specific to Rails).
