I am trying to get started using Rccp and decided to use Eclipse as a development environment since I already use StatEt for R. I am having trouble getting even a simple program to compile and run though, and would appreciate some help!

Briefly I tried to follow the instructions on the blog: <http://blog.fellstat.com/?p=170> exactly for setting up Rcpp, RInside and Eclipse, and for the example program. I am running on Mountain Lion, and installed g++ using the command line options in XCode. I think I've faithfully followed all the steps in the blog, but cannot get the program to compile. I think the problem is in the way the header files are included, as indicated from the snippet of the output below. As far as I can tell, line 52 of `/usr/include/c++/4.2.1/cstring` is an include statement for `<string.h>` and the compiler includes `Rccp/include/string.h` instead of the `string.h` from `std` that is found earlier on the include path. 

I am a novice in C++ so I'd really appreciate some pointers on how to proceed.
