The issue is that the scripts are redirecting stdout before calling dialog.
They rely on an unintentional feature of dialog which is documented in the
manpage:

       DIALOG_TTY     Set this variable to "1" to provide  compatibility  with
                      older  versions  of  dialog  which  assumed  that if the
                      script redirects the standard output, that  the  "--std-
                      out" option was given.

Also note that I broke the behavior of $DIALOG_TTY, but it is fixed in the
current package:
 
2004/03/01
	+ correct logic for $DIALOG_TTY, broken in 2003/11/30.  The environment
	  variable must evaluate to a nonzero integer (report by Florent
	  Rougon).

The current tetex-bin does not set the environment variable - that's needed.
