I've had the same problem with the linux version of povray 3.5. I either got
exit code 11 or a segmentation fault from povray, when I tried to run it as
a batch-job (executed by the at daemon).
Simply setting the DISPLAY variable to "0:0" (or some other display number)
in the script that runs povray works fine for me. There (usually) is no X
server running on that machine.
