The messages are warning, not fatal or non-fatal error messages. You can 
either redirect just the warning stream to /dev/null, or, more efficiently, 
you can use the "Warning_Level" INI option and set it to 0. This makes 
POV-Ray internally disregard the warnings relatively early, thus avoiding 
some overhead associated with sending warnings to the output stream.
