kdialog, xdialog, dialog missing?

Below is my build.log.
I don't think I'm missing dialog as I see the graphical interface up until it has its error.
But other than that, I'm not sure what my problem is here.
I'm basically just trying to do a basic customization without adding anything. I get to the point where it tells me to enjoy the ride, and then the next step is telling me that it failed.
Any thoughts are appreciated
