[Rcpp-devel] More Rccp and RccpArmadillo Errors on Mavericks

[Kevin Ushey]

Those ld warnings you're seeing, I think, are artefacts of the binary
version of R that you got from CRAN (someone else correct me if I'm
wrong). Basically, ld is searching for library-containing directories
that were used with the old versions of compilers, and warning you
that they don't exist. You can safely ignore these errors, or silence
them by creating empty directories at the locations it's searching in.
The fact that the linking step succeeds suggests ld is finding the
necessary libraries elsewhere now (as expected).
