Thanks, that indicates this test:

  (pass-if "open-input-pipe process gets (current-input-port) as stdin"
    (let* ((p2c (pipe))
           (port (with-input-from-port (car p2c)
                   (lambda ()
                     (open-input-pipe "read line && echo $line")))))
      (display "hello\n" (cdr p2c))
      (force-output (cdr p2c))
      (let ((result (eq? (read port) 'hello)))
	(close-port (cdr p2c))
	(close-pipe port)
	result)))

We had trouble with this one because of different shells.  The
open-input-pipe line was originally "read && echo $REPLY", but that
didn't work in Dash, so we changed it to "read line && echo $line" as
shown above.

Is it possible that your sandbox/package manager uses a different
shell from what is used when you run

>>>   ./pre-inst-guile -s test-suite/tests/popen.test

by hand, and that "read line && echo $line" doesn't work in the
sandbox/package manager shell?

Thanks,
