Suddenly: WDB could not be started?

I just joined you now because of this problem--probably answered
numerous times already...

I've been using ddd (3.3.11) for over a year now on my SuSE 10 box with
not too much trouble. Suddenly, yesterday, I launch it and get an
alert:

    DDD: No debugger

    WDB: could not be started.

    Exit     Help


The web tells me that wdb is some HP thing, so not too relevant and the
other debugger I most often use is, obviously, gdb. What changed on my
host that I can no longer use this? I'd like to get back up and
running.
