Yep.  I am rather inexperienced doing builds and such.  I need real good 
cookbooks like you supplied here.  Installed gcc, and nothing else was 
asked for.  I first cloned the card I have built up, and then ran your 
dd of the uboot.  Next to the cubieboard2 back together (monitor, 
keyboard, console, and the like) and watch the boot.
