Read the page again.
It says nothing about derivative works in the definiton of free software.

The GPL licence does not prohibit making a *commercial* derivative work
using the GPL'd software and selling it for profit, as long as the source
code is included and the whole derivative work is licenced under GPL as
well.
This contradicts the usage licence of POV-Ray, which expressly prohibites
using POV-Ray for commercial derivative works.

I'm sorry my original text wasn't clear. I meant that POV-Ray qualifies as
free software. IIRC the two licenses are compatable (not totally sure).

"It means that the other license and the GNU GPL are compatible; you can
combine code released under the other license with code released under
the GNU GPL in one larger program.
The GPL permits such a combination provided it is released under the GNU
GPL. The other license is compatible with the GPL if it permits this
too."
The POV license says it is incompatible with the GPL. The POV license
does not allow redistribution under the GPL. You may not use GPL code in
POV-Ray, you may not use POV-Ray code in anything but a fully-functional
version of POV-Ray distributed in a way allowed by the license. Again,
just read the POV license!
