No, you just drop the resource agent in the appropriate provider
directory (/usr/lib/ocf/resource.d/<provider/) and set its x bit. Then
it immediately becomes available to the LRM and Pacemaker.

Yes it does. Well, really it means you're using an elderly version of
the resource agents package which expects the heartbeat shellfuncs
library in a different location than the new RA.

If you change the path in that line 16 to
"/usr/lib/ocf/resource.d/heartbeat/.ocf-shellfuncs" (note leading dot in
filename and resource.d, not lib), then the RA should be able to find
the shell function library.

What's a much better idea though is of course to move to a recent
version of resource-agents, but that may or may not be an option for you.

Hope this helps.
Cheers,
Florian
