It looks as though you didn't install the Rtools collection. Take a
look in the Installation and Administration manual, Appendix E: the
Windows toolset. For compiling code you need the first 3 items: "the
command line tools" (which you seem to be missing), Perl, and the MinGW
compilers. Be careful to get your path in the right order, as described
there.
