I confirm that.

When studying the ticket created by Chris, I did a bit different from
you. Started at Introduction to Xorg-7.7 and then pressed "Next". The
same problem appears also in xcb-proto-1.9. Today, I stopped there.

I think the solution of including introduction as dependency for
xorg-proto and for xcb-proto seems to be a good solution.
