It's not quite as viral as that. He can license the code that he himself
wrote under whatever license he likes as long as it is compatible with the
GPL license of the other libraries that he is combining his code with. If
the code that he wrote is separable from HIntLib and GSL by rewriting that
functionality, he can distribute his code under the BSD license for
inclusion in SciPy.
