Is this the latest prerelease?
Do you mean that it worked before, then you installed wordworth and it stopped working?
Something is causing your Voodoo driver to crash, which is odd. Does Wordworth install anything in your startup-sequence, user-startup or WBStartup?
The error about gdb simply means you don't have the SDK installed, which isn't to do with the actual problem.
Edit: I notice you're a MAG member. Maybe someone from MAG could have a look at the problem in person? its always much easier to fix these things with the computer in front of you.
