It used some guerilla code that "knew better than we did" for loading; all that stuff changed way back when in 2012 (?) or so -- during Rcpp 0.9.*. This was simply stale code. With a simple change, it now passes R CMD check, for a suitable definition of 'passes'. I'll send you a pull request in a minute or two.
