OpenBSD renames the library in notmuch 0.39 from libnotmuch.so.5.6.0
to libnotmuch.so.1.2.  The next ABI change would rename it to
libnotmuch.so.1.3 or libnotmuch.so.2.0, following the rules in
https://www.openbsd.org/faq/ports/specialtopics.html#SharedLibs

To find the package version, run pkg_info -E like

$ pkg_info -E /usr/local/lib/libglut.so.7.0                           
/usr/local/lib/libglut.so.7.0: freeglut-3.2.2p0
freeglut-3.2.2p0    open source alternative to glut

This means that libglut.so.7.0 is from freeglut 3.2.2.  Another option
is pkg_locate (from pkg_add pkglocatedb).
