R help - May 2011 - Error Rscript: No such file or directory

Hello,
I'm trying to build a simple cpp file using the R CMD SHLIB command and I
always
receive the same error message:

cygwin warning:
  MS-DOS style path detected: C:/PROGRA~1/R/R-212~1.1/etc/i386/Makeconf
  Preferred POSIX equivalent is: 
/cygdrive/c/PROGRA~1/R/R-212~1.1/etc/i386/Makeconf
  CYGWIN environment variable option "nodosfilewarning" turns off this
warning.
  Consult the user's guide for more details about POSIX paths:
    http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
gcc -shared -s -static-libgcc -o hello.dll tmp.def hello.o Rscript -e 
Rcpp:::LdFlags() -LC:/PROGRA~1
/R/R-212~1.1/bin/i386 -lR
gcc.exe: Rscript: No such file or directory

Here is what I do:

* From the cpp file below: 

//file hello.cpp
#include <R.h>
void sayhello() {
 printf("Hello world\n");
}

* I build the file with the DOS command:

R CMD SHLIB hello.c


My confirguration is 
R 2.12.2
Windows XP 2002 SP3
I have installed the Rtools components and have included the following links 
into my path: 

C:\Rtools\bin;
C:\Rtools\perl\bin;
C:\Rtools\MinGW\bin;
C:\Program Files\R\R-2.12.1\bin

Thanks a lot for you help
Xavier

It looks as though you have somehow got some strange environment 
variables or contents of a Makevars file set, possibly because you have 
install Rcpp.  The "Rscript -e Rcpp:::LdFlags()" should not be there.
