ddd hangs on start-up with remote dbx

I'm running ddd locally on Linux (Redhat 7.0), and I'm trying to use
it with a remote dbx session running (by ssh) on a Sun.  When I start
up ddd, it just hangs after reading some shared libraries.  The
program I'm trying to debug is just a "hello, world" program, and dbx
works fine with it when I run dbx directly from the command line on
the Sun.

I saw in the list archives basically the same problem posted by
someone else about a year ago, but there was no answer.  Anyone know
what I'm doing wrong?  For various reasons, I can't just switch from
dbx to gdb.

Here's the output from "ddd --check-configuration":

Checking for X11 library directory... /usr/X11R6/lib/X11
Checking for XKeysymDB... /usr/share/xemacs-21.1.12/etc/XKeysymDB
No configuration problems found.


Here's the information for the remote host:

sundev2:~% uname -a
SunOS sundev2 5.8 Generic_108528-08 sun4u sparc SUNW,Sun-Fire
sundev2:~% dbx -V    
Sun WorkShop 6 update 1 Dbx Debugger 6.1 2000/09/12


Here's the ddd trace:
