[Rcpp-devel] Error: .onLoad failed in loadNamespace()

[Romain Francois]

Works fine for me. Laurent, can you try with the current svn version of 
Rcpp.

svn checkout svn://svn.r-forge.r-project.org/svnroot/rcpp
cd rcpp/pkg
R CMD INSTALL Rcpp
Rscript -e "require(Rcpp); Rcpp.package.skeleton(module=TRUE)"
R CMD check anRpackage
