Andrew,

this is a pure ctdb patch.
Samba's samba-ctdb target does not build or test ctdb,
it only builds samba with clustering enabled.

We can try to ensure it gets built in the ctdb build,
but it has dependencies, so we would need to protect it
with configure checks, and without installing libpcp-pmda3-dev
and some other packages it would not get built.

Once we have ctdb in the samba tree and autobuild system,
we can ensure that it always gets built and can avoid
regressions.
