I was wondering if we could make it a run-time dependency though .. a
bit like get_cluster_name.  We can still do that later I guess.  I'm
not really sure what is best at the moment.

Yes, I would second that: Making these functions a run-time dependency.
We should have the ability for it to work by just installing libdlm
(with the proper flags set), rather than recompiling the package for
cluster features.

Or - maybe unlikely but maybe not - what happens if somebody installs a
binary that was built on a system WITH dlm, but is meant to run on a
system WITHOUT dlm?

Actually, wouldn't that be the typical case for a typical distro?

That's exactly the case we are trying to cover in the above explanation. 
IOw, we would be using -ldl for runtime compatibility. If libdlm is not 
present, cluster functions will be resolved to null and will not be 
executed/allowed.
