Oh, come on, don't be so complicated.  It clearly says:

" EXCLUSION FROM STANDARD LICENCE PROVISIONS

 Software authors may use this source code in derived programs PROVIDED
 thay they comply with the terms of POVEXT.TXT."

And in POVEXT.TXT it says:

"Extensions may be based on the 'extension toolkit' source code we provide.
That is, we explicitly permit you to re-use our demonstration source code
(and in fact encourage it, since it helps ensure that you comply with our
standards.) This permission DOES NOT extend to other POV-Ray source files."

So if you comply with it, you may use this source code.  Very easy, isn't
it?  The source code is copyrighted and provided to you under the given
license.  Obviously you have to refer to the given license when making it
available.  But the changed source code remains your copyrighted program, of
course.
