Sure, and those are documented at the bottom of the README. My
suggestion is to add 'patch' to that list.

As I mentioned, of course it's reasonable. It's not in Debian
'required', however, and the requirement wasn't there before, so since
the team went through the effort to document the build requirements, I
assumed that notices of changes to that list would be appreciated.

The Xen build system "bails" automatically as it's written now. You get
a fatal error if g++, X11, or others are not present :)
My feedback here is the same as well. As long as the build requirements
are documented in the README, I'm a little bewildered if the team
doesn't want to keep that document up to date. Adding g++/X11 seemed a
fairly large leap over the lean build requirements previously needed.
I'm autobuilding Xen for the XenCD work. That building is automated and
done within a controlled environment (Debian debootstrap "required"
built every time). So I'm catching changes to the build requirements
that others are perhaps not. (BTW, I had to move this direction because
I was building a debootstrap dom0, and if I built Xen outside my dom0, I
would get libc link errors of 2.3.3 vs 2.3.4, for example).
If you'd prefer that I skip notifying the team when I notice changes
needed to that environment, that's the way I'll proceed. Otherwise, I
presume you'd like to at least hear of needed documentation changes,
even if no action is taken. Of course, you'd prefer patches instead of
whining and sometimes I do send patches along with suggestions. But
right now I'm just focused on working around any such issues in order to
get to a XenCD prerelease.

That would of course be reasonable. Since I'm not providing that patch
at this time, this can either stay as merely an issue for the mail
archives, or can get put onto some wishlist roadmap the team maintains.
