Your just-uploaded-to-CRAN version 1.2.3 has the Depends on "Rcpp (>= 0.11.0)". Which is really needed given that we no longer have a library to link against. So you may as well take advantage of this: this pull requests removes the now spurious call to Rscript to ask Rcpp about the library location and name. Because with Rcpp (>= 0.11.0) you only get an empty string back anyway.
