Of course, and once you reimplement GSL then you can say that the software 
does not depend on GSL for its functioning. But until you do, if you 
distribute software and say "this will only work with GSL because no other 
implementation of that API exists" then you have a derivative work.

Don't you think the message "Can Technical Tricks Circumvent the GPL?" by 
RMS is clear enough?
If your software *depends* on GPL software it must be GPL. Technical tricks 
to circumvent this dependency are just that: technical tricks.
