In general, you can't depend on that, since the latest checkout
might be on a different slave.
If you want to refer to the results of a previous builder, you
may have to save them somewhere in a build step at the end of that builder,
and then retrieve them in a build step at the start of the builder
that depends on them, e.g. using scp.  That's what I do.
(Well, on the Mac and Windows, I use scp; on Ubuntu, I use apt for
retrieving artifacts that have been packaged as .deb's.)
