  Strange...  I have a CGI shell script that runs x-povray.  I can
tell you that it works.  As a CGI (that is, when called by Apache), or
as a standalone program (that is, on the Linux console, without any X
server running).

  Try analysing the output of POV-Ray (I mean, the textual part).
Mine gives:
