This is not the complete text output from POV-Ray, if you don't know how 
to obtain it use:

megapov [options] 2>&1 | tee render.log

This does not make much sense, esp. not in the 8th frame of an 
animation.  The previous frames must have parsed without problems so 
either the functions.inc file got messed with after frame 7 or you have 
some really serious trouble with your system (there isn't any reference 
to 'internal(-1)' in the normal functions.inc).

BTW /usr/share/povray-3.6/include/ is a nonstandard location for 
functions.inc, the standard is /usr/local/share/povray-3.6/include/.
