   (display "Hello, world!" 
      (open-output-pipe "mimencode"))

   should write `SGVsbG8uIHdvcmxkIQ==' to the `current-output-port'?

   It does not.

   It seems, it writes to the "stdout", but I do not understand, how to
   get these data back to guile (in interactive mode, I see the output
   only after finishing guile session).

the port returned by `open-output-pipe' is not closed when `display'
finishes.  buffered output is flushed on close.  try this:

	(let ((out (open-output-pipe "mimencode")))
	  (display "hello world" out)
          (close-pipe out))

i also tried:

	(with-output-to-port (open-output-pipe "mimencode")
	  (lambda ()
	    (display "hello world")
	    (force-output)))

but this did not work for me.
