Would it be an option to provide a jhbuild script that can be used to
automatically build everything from source? That should at least remove
any ambiguities or distribution specifics and should always work. Doing
so has two advantages: it is a script and therefore can save everybody
from a lot of typing (or copy/pasting) and it documents the origin and
exact command sequences required to build from source.

If not everything is to be built from source there is apparently also a
way to specify dependencies (via pkg-config files!) that are assumed to
be installed by the distribution.

I think back in the early days many people used jhbuild to build modular
X, though its usage seems to have declined. But perhaps that's just
because its so common that nobody considers it worth mentioning anymore
or X has stabilized to a point where building everything from source is
no longer required.
