I don't think so. Most of the Numerical Recipes code is itself cloned from 
published articles. It's easy enough to clone it by going back to the original 
sources. I doubt that the NR license would even be enforceable, in general -- 
their code often even uses the same variable names as were used in the original 
Algol code! There's not much original code in NR. (The big contribution of NR 
was to collate all the algorithms).
