Thanks Doug and Rob -- I've followed the guide with one deviation -- I
disabled distcc and ccache... otherwise I did exactly what the guide
stated.

I'm going to do as Doug suggested and then recompile qt, I believe
someone told me qt also needed debugging stuff enabled.

Here is the latest (and different) backtrace that I have:

This one is different than the others... either because debugging is
enabled properly or I have multiple problems :-\

Thanks...
