| Setup Procedure:
| 1. Downloaded the R binaries for OSX (R version 3.0.2 (2013-09-25) -- "Frisbee
| Sailing")
| 2. Installed Rcpp (0.10.5) and RInside (0.2.10)from within R (used
| install.packages(file_name_and_path, repos = NULL, type="source"))
| 3. ran CMake (2.8.12) on the RInside examples/standard in a separate build
| directory
| 4. ran make (compiler is Clang 4.0)

It should also work without step 3. The CMake files are contributed and
optional; their focus is on help with certain IDEs with use CMake (and for
CMake itself).  But they may not have been tested as much on OS X.

So go to examples/standard, and instead of 'make' (ie 'make all'), let's just
make one:

edd at max:~/svn/rinside/pkg/inst/examples/standard$ rm rinside_sample0
edd at max:~/svn/rinside/pkg/inst/examples/standard$ make rinside_sample0
ccache g++-4.7 -I/usr/share/R/include -I/usr/local/lib/R/site-library/Rcpp/include -I/usr/local/lib/R/site-library/RInside/include -g -O3 -Wall -pipe -Wno-unused -pedantic -Wall    rinside_sample0.cpp  -L/usr/lib/R/lib -lR  -lblas -llapack -L/usr/local/lib/R/site-library/Rcpp/lib -lRcpp -Wl,-rpath,/usr/local/lib/R/site-library/Rcpp/lib -L/usr/local/lib/R/site-library/RInside/lib -lRInside -Wl,-rpath,/usr/local/lib/R/site-library/RInside/lib -o rinside_sample0
edd at max:~/svn/rinside/pkg/inst/examples/standard$ ./rinside_sample0
Hello, world!
edd at max:~/svn/rinside/pkg/inst/examples/standard$ 

The exact linking statement will be system-dependent but you need to show us
yours.  What you show below is a) 'too late' and b) lacking detail.
