Current Git version doesn't build

[[Unknown]]

You forgot to run git submodule update --init (which is not surprising and everyone does, but it should be in the wiki, if it isn't let me know where.)

In general, I recommend cloning git repos with --recursive. I'm not really sure why it's not the default. This alias is not a horrible idea:

git config --global alias.clone = 'clone --recursive'

This will make it run git submodule update --init --recursive for you after cloning.
