Any way we can print a more descriptive error at failure time instead of
just hiding a clue in the docs?  Or can we just disable docbook if deps
aren't present?

I'm not certain Arch will be the only distribution to ever have this
problem, and the comment could get a little unwieldy...

(Why is this reaching out over the internet anyway?  Is this a bug that
should be brought up with an Arch package maintainer?)
