 From the above code I presume you're using the Linux version of POV-Ray.

Make sure that before you build POV-Ray, the SDL (Simple DirectMedia 
Layer) library development package (SDL-dev I guess) is installed on 
your computer. If this is not the case, POV-Ray cannot build with 
preview window support.

As for POV-Ray 3.6, my guess is that you might have obtained it as a 
pre-built binary with the SDL library linked statically.
