Should gnome-doc-utils be a git-build dependency, now? (automake error)

automake-1.11: cannot open < gnome-doc-utils.make: No such file or

Is gnome-doc-utils a new dependency?

I see the changelog entries adding and tweaking the manual, which 
presumably triggers this, but can it be made optional?  As I'm a kde guy 
I'm not particularly eager to have to install scrollkeeper and gnome-doc-
utils, but with just the one package and one additional pulled-in 
dependency, I guess it's not /too/ bad, so I probably will if I have to, 
particularly since knowing what the manual says will no doubt be of help 
answering questions on the user list.  So I probably will install it if 
necessary for the manual, but I thought you should be aware of the new 
dependency in any case.
