Hi, Thanks for the help.
Putting the call to Rscript directly in the definition of PKG_LIBS rather than in a different makefile variable and using that variable when defining PKG_LIBS did indeed fix my problem.

On unix it's as simple as PKG_LIBS=`${R_HOME}/bin/Rscript -e 'whatever.you.meant.to.run()'` and on Windows it's PKG_LIBS=`${R_HOME}/bin${R_ARCH_BIN}/Rscript.exe -e 'whatever.you.meant.to.run()'` Note that you should NOT mess with the environment variables that R uses as you're likely to set them incorrectly.
