I hope it is ok to ask questions here. I'm not a really all that proficient
in Linux, so sorry if this is a dumb question. I've looked over the manual
and known problems, but didn't find anything relevant.
I am using Emacs 23.3.1 with ghost script 9.04 on Ubuntu 12.04
The problem is I get nothing but red signs when trying to generate
previews. The error messages are incomprehensible to me. Here is one from
an attempt to render a simple $A$ at a point:
gs -dOutputFile\=\(_region_.prv/tmp6465dBV/pr1-1.png\) -q -dSAFER -dNOPAUSE

Using all my powers of logical deductive inference I presume the "gs" at
the beginning of the error message indicates the problem has to something
to do with ghostscript, but I'm not sure of what the rest means. I could
pour through the ghostscipt docs but I was hoping perhaps I could get a
helpful hint here to focus my efforts. Any helpful hints would be greatly
appreciated :)
