On Solaris and Linux /dev/stdin, /dev/stdout, and /dev/stderr are device names for standard input, standard output, and standard error. /dev/stdin is occasionally useful when piping data to a recaltricant C program which doesn't read from standard input or recognise '-' as a synonym for standard input. Likewise for the others. In your case you would set $logfile = "/dev/stderr"; of course this will only help you if your OS supports /dev/stderr. /dev/fd/2 might be another option for standard error. On Solaris, man -s 4 fd for details.
