[Rd] Detecting development environment

[Hadley Wickham]

Hi all,

Is there a straight-forward, cross-platform way of determining if a
user has all the tools needed to develop R packages (i.e. gcc etc)?
It doesn't need to be 100%, but should give a rough idea.  One idea I
had was simply to see if system("R CMD install --help") worked.
