Ups, yes, that isn't included there in the standard distribution, I only had
it in my local copy for tests...

You can either use the command-line "-w384 -h384 +a0.3 +v -d -f -x"
suggested in the benchmark scene file's comments, or you render the built-in
benchmark file once and extract the benchmark scene/INI file from the
temporary directory.  This is what I recommend to do as it will make sure no
Mac dialog default settings interfere:

1. Render the built-in benchmark once.
2. In the message window, locate the render options section. It shows where
   the scene file is located.
3. If the file was for example
     MyDisk:private:tmp:501:TemporaryItems:benchmark.pov
   copy and paste this message into some window and edit it so it looks like
     /volumes/MyDisk/private/tmp/501/TemporaryItems/
   then you can in the Finder go to the directory directly using the "Go to
   Folder..." function in the "Go" menu.
4. Open this benchmark.pov file in POV-Ray and specify the benchmark.ini on
   the command line.
5. Render the benchmark.

Alternatively, you can of course just copy the benchmark.ini file from the
above folder to your :scenes:advanced: folder.

object.pov is the default name POV-Ray assumes if no file was specified.  It
is a follow-up error to the missing ini file.

Argh, yes, that is an internal error in the just-in-time compiler.  It will
insert the hardware square-root function but assumes the software
square-root function is used in the validation stage (only the G5 has a
hardware square-root function).
