/usr/pkg/lib/libImlib2.so.1 comes pkgsrc packages.
Others -- from NetBSD sets (base.tgz, comp.tgz, xbase.tgz and others)

Normally pkgsrc binary package contains files under /usr/pkg
(or another prefix specified at build time by user) but
not in /lib, /usr/bin, /usr/local etc. There are only a few
exclusions, for example, compat50-5.1.tgz, but its purpose is
different.
