One should *not* run ldconfig on the directory holding the backends,
ie ${sanelibdir}.  Frontends should link against libsane which is in
${libdir}.  If one absolutely insists on running ldconfig it should be
run on ${libdir}.

IIRC, Mandrake (before it became Mandriva) and Turbolinux had bugs in
their %postinst sections that ran ldconfig on ${sanelibdir} and broke
their SANE installations.

Hope this helps,
