Hello, I might be wrong but, as far as I know, the licenses apply to code and not to algorithms. That is, once you jump out of the original implementation (the original codes are not in d) and you re-implement the algorithms in another language (in this case d) the work is not, properly speaking, a derived work. I insist, I'm not a lawyer and I'm not 100% sure but that could be checked. Cheers!
