Jeff, is this the recent version of MinGW, Perl and the tools?

Yes, MinGW, and the tools which are based on some cygwin sources, AFAIK.
But you must not have any other cygwin directory in your path.
As you can see from the Windows binary package section on CRAN, building
packages works perfectly well for us.
If it still does not work for you, you might want to start from scratch
by cleaning up your path and following the instructions given in the "R
Installation and Administration" manual.
