You forgot to take the compiler into account...the version of gcc in the 
development tools is nowhere near as good at optimization as Metrowerks 
CodeWarrior (which is used for the official version). The next update of 
the development tools will use a more up to date version of gcc which is 
apparently much better at optimization of PPC code, I don't know how it 
compares to CodeWarrior. If you want to compare 3.1 and MegaPOV, compile 
MegaPOV with gcc as well.

And anyway, being a GUI program won't really affect the render 
speed...you probably ran the command line version from Terminal.app, 
which (obviously) is a GUI program itself. The only way there could be a 
significant difference is if you booted up without any GUI at all, which 
I don't consider worth the few % of CPU time gained. Just being a CLI 
program doesn't give any special advantages.

There may be something specific to how POV-Ray Mac works though...maybe 
the way it handles events uses up CPU time or prevents it from using 
100% of available cycles.
