[R] can't R CMD INSTALL on WinXP

Dear All,

I recently got a laptop upgrade, and had to re-install the tools I used
for building R packages on Windows (XP SP2).  I'm running into a strange
problem that I can't resolve.  Can anyone shed on light?  This is with
R-2.7.2 patched 2008-09-20 r46576, Rtools.zip downloaded a couple of
weeks ago, and MikTeX 2.7.  The output below was from a cygwin shell
(PATH modified apropriately), but it's identical to what I get under
Windows command prompt.  I've also tried adding the -l flag to install
in another directory that I'm sure is writable, but same problem.

$ R CMD INSTALL -c randomForest
installing to 'c:\R\library'
