[Rd] Vignette using parallel's makeCluster function has trouble building on Windows 7

Hi, all--

I've been working on a doParallel package to provide a foreach parallel backend for the new parallel package, but I am having trouble building the vignette. On my system, if I use the following minimal vignette (call it buggyVignette.Rnw):

   \documentclass[a4paper]{article}

   \title{Sweave Example 1}
   \author{Rich Calaway}

   \begin{document}

   \maketitle

   In this example I try to run code using library parallel in a vignette:

   <<>>=
   library(parallel)
   cl <- makeCluster(3)
   @

   and find that I get an error.

   \end{document}

I get the following error when I try to build the package:

   C:\Users\richcalaway\RforgeDev\doparallel>C:\R\R-2.14.0\bin\R CMD build pkg

If I simply comment out the line with the call to makeCluster, the package (complete with vignette) builds. Also, I can use R CMD Sweave/pdflatex together to produce a PDF without error. Has anyone else encountered this problem, and if so, how did you fix it? I can work around the problem if need be by converting the code chunk to a LaTeX verbatim, but that doesn't seem very vignette-friendly.

Any help would be greatly appreciated. Below is my sessionInfo and my current path
