Unfortunately, as much as I love the GPL, I don't think this is
enforcable.  Remember that the GPL covers only distribution, not use;
hence, if the distribution of a work linked against a library
interface (even that for which only a GPL'ed implementation exists)
does not contain any actual code from that library, it cannot be
considered a derived work.  Although IANAL, it would be like suing
critics for reviews which contain "hooks" into the book (e.g.,
character names, chapter and/or event references, etc.)
