One of the error messages that you supplied said that XF86Config was not created. When dselect tries to configure xbase, it is trying to create /etc/X11/XF86Config, and it appears to be failing on your system. So you don't have an XF86Config file yet. dselect runs some graphical X configuration program when it tries to configure xbase, but you can also configure X by running the command xf86config, which walks you through a bunch of questions about your mouse, monitor, card, etc. You might give it a shot.
