You're done!

Possible errors:

• Error with makeinfo. Solution: Install makefile 3.82 package
• Error with sanity checker.

Solution:

Comment out last line in meta/conf/sanity.conf to disable sanity checks set bbpath to poky/rpi-build ($BBPATH)

remove debug-tools from rpi-build/conf/local.conf

From now, build gaia on top of it.
