Fresh org pull, same file... no viable output. The =set output "test.eps"=
command with no :file header does not work. I get "code block produced no
output" in the minibuffer.

Here's some things of interest...
-- Removing =set terminal...= and exporting via =:file test.png= works
-- Using =set terminal postscript= and =:file test.ps= works
-- Using =set terminal postscript eps enhanced= and =:file test.eps= does
*not* work

What package provides the eps ability? Perhaps I removed something from my
system that I didn't intend to!

Any suggestions on how to see what's going on?


Thanks,
