[R] Regarding {KernSmooth} - Can a package on CRAN have non GPL copyrights?

[Joshua Wiley]

AFAIK CRAN does not explicitly require use of a GPL license (though
obviously the license needs to allow at least free access to the
packages and source).

Well, I think that is just a warning that it was built under a
different version of R than you are currently running it under.

If memory serves, the current KernSmooth is a port to R by Brian
Ripley; that message suggests the original KernSmooth was copyrighted
by M. P. Wand from 1997 until 2009 (probably the original author in
S?).
