Fabrice,

	Yes, since the merge was made in LSST/external/xrootd.git.

	Correct.  This is what buildbot uses by default as well.

	That should never be the case.  Master is not allowed to be
broken :-).

	Hopefully this is a rare situation, but in that case you would
need to be able to specify the appropriate dependencies.  You do this by
specifying the git versions of the repos you want to build, either
through branches or tags, using the "-r" option to rebuild or the --ref
option to lsst-build.

	That's correct.  The distribution server (currently) only
contains *released* packages, not the buildbot-built packages.  To use a
buildbot-built package, you need to login to NCSA and use the buildbot
stack, ~lsstsw/stack (or, equivalently, ~lsstsw/eups/bin/setups.*).

	If there's a particular version you want to release, along with
its dependencies, the ~lsstsw/bin/publish script needs to be run to do
that.  Eventually we will have buildbot automatically create
distributions for (some) successful builds (perhaps nightly), but that
hasn't been implemented yet.
