I can reproduce your problem in my 10.6 VM. std::log2() is only defined if the internal macro __GLIBCXX_USE_C99_MATH_TR1 is defined. This is not true for 10.6 (but for instance for 10.9.) I do not know off-hand why this is not the case on 10.6. Maybe Google can help you to determine how/when this gets set? Mihai
