Both devtools and Rstudio check if gcc and ls are on the path already,
and if they are, do nothing, so anything you did should be compatible.
 JJ and I would of course be happy to make any changes if necessary,
and share our code for Rtools detection (along with useful error
messages in all the edge cases).
