- Add new port: devel/R-cran-sys

Drop-in replacements for the base system2() function with fine
  control and consistent behavior across platforms. Supports clean
  interruption, timeout, background tasks, and streaming STDIN /
  STDOUT / STDERR over binary or text connections. Arguments on Windows
  automatically get encoded and quoted to work on different locales.
