From ChangeLog: 2011-12-29 Dirk Eddelbuettel <edd at debian.org> * src/RcppArmadillo.cpp: Force instantiation of arma version vars which helps with older OS X compiler, as suggested by Gershon Bialer and this is now in RcppArmadillo 0.2.35. Please try that, which itself will need Rcpp 0.9.10. Let us know how it goes. Cheers, Dirk -- "Outside of a dog, a book is a man's best friend.
