>From install.packages in utils/R/packages2.R:

      if(missing(lib) || is.null(lib)) {
        lib <- .libPaths()[1L]
        if(length(.libPaths()) > 1L)
            warning(gettextf("argument 'lib' is missing: using '%s'", lib),
                    immediate. = TRUE, domain = NA)

  If I were patching this I would simply comment out this whole test (rather than making a message() √† la Jari Oksanen) -- it seems to make the most sense to execute the documented behavior silently ...

  I will submit this as a wishlist item shortly if no-one complains.
