[R] What a contortion of the GPL.

Concerning this licensing from the Design library:
> ### GENERAL DISCLAIMER This program is free software;
> ### you can redistribute it and/or modify it under the
> ### terms of the GNU General Public License [...]
> ### with the exception that you may not port any code
> ### in the Design library to R. [...]
> ### In short: you may
> ### use this code any way you like other than porting
> ### any of the code to R, as long as you don't charge
> ### money for it, remove this notice, or hold anyone
> ### liable for its results. [...]
This is kind-of amazing, I've never seen anything like it. I can't
imagine a reason why a person would make this restriction, but I guess
there is an interesting story behind it? I do think the exception
stated violates the GPL itself, and so a lawyer would argue that this
copyright is effectively meaningless.
Now, concerning the terminology "port the code to R", since I'm not a
programmer, I can ask this with a straight face: is there a wedge
between the R distribution and the programs I write that access R?
Obviously, R can't assimilate this code into the R distribution, but
maybe it does not stop a person from making a personal use of this code
in his own programs. After you finish laughing, nod once for yes and
twice for no.
