This is as close to nonsense as it can be, please stop this quest of 
yours to advertise problems that do not exist and RTFM

we do get a trivial warning on linux which has already been fixed, and 
0.8.4 has not been cran processed under OSX but we have evidence that it 
works. solaris is a different matter.

The author of that package chose to not follow the documented way to 
pull in the headers , which is as I told you before to add

LinkingTo: Rcpp

in the DESCRIPTION file

Also, see this thread on R-devel on how to invoke Rscript from Makevars 
correctly, which incidently is also documented in the "Rcpp-extending"
