Hi, According to CRAN Package Check Results for Package, http://cran.r-project.org/web/checks/check_results_Rcpp.html it has an error on Solaris. I have a package using Rcpp. My CRAN Package Check also says it has error on Solaris. It's from dependency of Rcpp. How can I avoid this error on Solaris? For example, can I set Rcpp version lower?
