      These environment variables must be set before the download code
      is first used: they cannot be altered later by calling
      'Sys.putenv'.

Also, Sys.putenv("http_proxy"="http...:8080") sets that to the value in "" and not the value of a variable named that: for the latter you must use `` quoting. This is I suspect the actual failure cause.
