You appear to have a space in the installation path, see how the line broke
after C:/Program and continies with Files/R/R-2.13.1/....

You may have to install R in a different location -- I personally put open
source stuff onto c:/opt/ so for me it is often c:/opt/R/R-current/ (and the
R-current name avoids the silly renamed of $PATH etc for each new version). 

So yes it all works if you avoid paths with spaces. I was about to link to
the 'checks' on the CRAN website but those links are currently broken :-/

If you want to keep your current location you may have to rework all the
Makefiles to not autocompute the path of Rcpp and RInside as that is where it
breaks.

Hope this helps,  Dirk
