Autobuild does do a standalone CTDB build and runs the CTDB test
suite.

This problem was a bit subtler, so it would be hard to try to catch in
autobuild. During a CTDB RPM build the new private library was built and
installed, and then it fell over at the last hurdle due to an
unpackaged file (libiov-buf-ctdb.so, I think).  Testing that in
autobuild is probably over the top.

Perhaps I should produce a patch that adds some comments to
lib/util/wscript_build, politely asking those editing the file to add
new private libraries in the section that starts with:

  if not bld.env.SAMBA_UTIL_CORE_ONLY:

At least then this would be clearly documented.

This is more my fault that Volker's because I've introduced an
unnatural division in lib/util/wscript_build.  Having done that, I
should have clearly documented it.

Unless someone thinks I'm crazy (in this particular respect ;-) then
I'll do that tomorrow...

peace & happiness,
