Indeed.  So I think you need to modify
‘daemons/dmeventd/plugins/mirror/Makefile’ or otherwise arrange to have
‘-Wl,-rpath=OUT/lib’ passed when linking
libdevmapper-event-lvm2mirror.so.

Packages using Libtool don’t have this problem because Libtool relinks
upon installation so that the installed binaries have the right RUNPATH.

HTH,
