No, I may have been overzealous.  After all, RcppArmadillo builds and so do
the eight packages already depending on it (start here at long at per-package
build results incl OS X: http://cran.r-project.org/web/packages/RcppArmadillo/index.html

It is true that OS X is stuck at g++ 4.2.1 but both Conrad (for Armadillo)
and us (for RcppArmadillo) have so far managed to code around the
restriction.  

So as Conrad wrote to me and Terrance in off-list email, this may "just" be a
matter of an older Armadillo library being on the machine where Terrance
tried this. I can't test this on OS X for lack of a machine.

Lastly, RcppGSL is a proof of concept with a much worse interface. If you
can, use RcppArmadillo for your projects.
