You want to run "make chain-build" from the last package in the chain.
This makes sense because you will have needed to bump the revision in
the spec and run "make tag" for each of the previous packages in the
chain already.  So, if foo BuildRequires bar and bar BuildRequires baz:

cd foo/devel
<bump spec and commit>
make tag
cd ../../bar/devel
<bump spec and commit>
make tag
cd ../../baz/devel
<bump spec and commit>
make tag
make chain-build BUILD="foo bar"

Which will build foo, wait until it appears in the repo to build bar,
and then wait until bar appears in the repo to build baz.

I'm going to see about rolling ajax's chain-build-expert patch in, for
finer control of build groupings.
