This is *excellent*. Thank you *very* much Andrew! Well done!

I'm happy now! *G*

In order to solve this I added samba-cluster-support into the deps
in smbd definition in source3/wscript.  But the dependency forest
itself is not trivial, I don't have time/energy now to dig there
further to understand where the dep should go.  The missing symbol
(messaging_ctdb_connection) is used in source3/smbd/{process,server}.c
so this suggests it should be added to smbd link line as a direct
dep. Or, it seems, to smbd_base deps since this is where the
mentioned sources are actually listed.  Should be easy to do for
someone who is more familiar with the set of modules/subsystems
and the rules of the deps.

This is an interesting issue by its own, I hit it once again, it
deserves a separate email.

Thank you Andrew!  We're getting close :)
