When importing the weapon you need to uncheck the "append to existing model" option. Then go into pose mode and add a Copy Transforms constraint to the weapon bone, targetting the character bone with the same name.

What are you importing, and in which exact order? It would help if you uploaded your blend file.

You'd do better asking this in the Blade Symphony forums.

I can export a cell fractured object without any issues now, without any bones anywhere. Can you upload your blend[www.pasteall.org] for me to take a look at please?

Download the beta again and things should work.

If new items appear after an export, you are probably running Blender in debug mode 2 or higher. Reduce the value with Ctrl+Alt+D.

You should Group all the fractured objects together. Unfortunately exporting vertex animations for groups isn't working, so bear with me on that.

Here's a beta release, let me know if anything could be improved.

This is news to me! I'm looking into it.

Although Source does support shape keys, it doesn't support full-on vertex animation. All you can do is move verts in a straight line between two positions.

One way or another you're going to need to rig your mesh up with bones and animate them.
