My personal approach is to follow the path of least resistance on __start

Rcpp comes with modules-using packages as part of the documentation (Rcpp
modules vignette) and unit tests. And there is even a package skeleton
generator (for which you can set an option to use modules). 

And among the now 55 CRAN packages using Rcpp (!!), a few use modules
too. One is my RcppBDT package, there are the two packages by Baptiste (cda,
planar) and probably a few more but one can't tell from the DESCRIPTION.

Your code may have been fine, but you also need to look at the .onLoad or
.onAttach function etc.  So starting from a working stanza really strikes me
as easiest.

Hth, Dirk
