Nice, and it should thanks to BH and its headers. 

OS X won't have OpenMP support (yet, apparently some future version will).
But Linux and Windows should be fine.

|     | Yes, using a single header parallel RNG, which is compatible with C++11

|     I owe you a follow-up (maybe later today) about how/where it built for me

|     |     Yes.  For the two (smaller) packages (RcppCNPy, and RcppBDT) where I
|     use
|     |     C++11 features I have
|     |
|     |           Depends: R (>= 3.1.0)
|     |
|     |     and you should too as C++11 does need R 3.1.0 or later.

|     | Thanks, Prof. Ripley pointed at the same solution.
