[R] Building from source under Windows 7

I have downloaded all of the tools and read the readme's that I know about but I am still getting the following error when I try to build from source:

C:\Program Files (x86)\R\R-2.9.2\src\gnuwin32>make all recommended
make[1]: `Rpwd.exe' is up to date.
cp -p etc/Makeconf etc/Rcmd_environ etc/Rconsole etc/Rdevga etc/Rprofile.site et
c/rgb.txt ../../../etc

make[1]: *** [rbuild] Error 2
make: *** [all] Error 2

C:\Program Files (x86)\R\R-2.9.2\src\gnuwin32>

I have given myself full control on all of the directories and files yet I am unable to get rid of this 'Permission denied' error. Anybody out there that has similar problem building 2.9.2 under Windows 7 x64?

Thank you.
