Have you compiled Rcpp from source ?
If not, are you compiling with the same compiler that was used to
compile Rcpp.
The cran binary for Rcpp 0.10.6 was built with llvm-g++ wherehas
preseumably you are using clang now on Mavericks.
Please try compiling Rcpp from source.

Hi,
I just got started using Rcpp after spending a fair amount of time working in
the two separately. I'm currently running into some errors with c++ code that
tries to use the matrix classes in Rcpp:
library(Rcpp)
cppFunction("int mwe() {NumericMatrix mat(1,1); return 0;}")
Error in
dyn.load("/var/folders/zf/w0dsd0yn3d7czjqv5rbj9xph0000gn/T//RtmplA25bk/sourcecpp_fb48bcd5d63/sourceCpp_14740.so")

This is the same basic error I get when I try to run the RcppGibbs.R example or
Rcpp-unitTests.R. C==filt says the
I'm currently on OS X 10.9 with R 3.0.2 and Rcpp 0.10.6.
Does anyone know how to fix this?
Best,
