BBB ubuntu problem installing SGX kernel 3.15.8-bone6

This seems new:
I flashed the latest ubuntu console image to my BBB: BBB-eMMC-flasher-ubuntu-14.04-console-armhf-2014-08-13-2gb.img
I update the repositories & upgrade (sudo apt-get install update, sudo apt-get upgrade)
I then follow the instructions to update to the special SGX kernel. git pull, then:

ubuntu@arm:/opt/scripts/tools$ sudo ./ --kernel v3.15.8-bone6

[sudo] password for ubuntu:

I get lots of errors and build fails.

Is this temporary?

Has something changed?
