OK, I can reproduce this problem if the executable isn't in my path:

[node@trust bin]$ x-pvmpov foo.ini
Persistence of Vision(tm) Ray Tracer Version 3.1g.Linux.gcc
  This is an unofficial version compiled by:
  Jakob Flierl <fli### [at] lugade> - PVMPOV Version 3.1e.2
  The POV-Ray Team(tm) is not responsible for supporting this version.

...spawn failure because executable not found.
...No tasks spawned!  Quitting.
[node@trust bin]$ ~/x-pvmpov foo.ini
Persistence of Vision(tm) Ray Tracer Version 3.1g.Linux.gcc
  This is an unofficial version compiled by:

(and it renders)

Hope this helps,
