Indeed.  So I think you need to modify
=E2=80=98daemons/dmeventd/plugins/mirror/Makefile=E2=80=99 or otherwise arr=
ange to have
=E2=80=98-Wl,-rpath=3DOUT/lib=E2=80=99 passed when linking
libdevmapper-event-lvm2mirror.so.

Packages using Libtool don=E2=80=99t have this problem because Libtool reli=
nks
upon installation so that the installed binaries have the right RUNPATH.

HTH,
