Looks like neither your R binaries nor Rtools directories are in your system's PATH environment variable. Try this:

> writeLines(strsplit(Sys.getenv("PATH"), ";")[[1L]])
C:\R\Rtools\bin
C:\R\Rtools\gcc-4.6.3\bin
C:\R\R-devel\bin\x64
[... and so on ...]

If your directories C:\R\R-3.0.1\bin\x64\ and C:\R\Rtools\bin\ & C:\R\Rtools\gcc-*.*.*\bin\ (replace \gcc-*-*-*\ with your version of the gcc-binaries) are not listed, the needed components can't be found. To be on the safe side, also create a system variable called CYGWIN with the value nodosfilewarning.

After changing/creating the PATH and CYGWIN variables, reboot. Then it should work and you can place your sources anywhere on your machine and also compile them manually using R CMD SHLIB.
