Don't seem to have a libsane-dll anywhere in /usr.  Do have libsane-v4l.la, .so.1, and .so.1.0.22 in /usr/lib32/sane and /usr/lib/x86_64-linux-gnu/sane .

/etc/ld.so.conf only has:
include /etc/ld.so.conf.d/*.conf

... and /etc/ld.so.conf.d only has files named:
libc.conf
x86_64-linux-gnu.conf
zz_i386-biarch-compat.conf

Both machines are running the most current Debian Testing 64bit.  Didn't build from source;  did a network install.

Don't have a /usr/lib/libsane.so*  or  /usr/lib/sane/libsane-dll.so*  on either machine.
Neither also in  /usr/lib/x86_64-linux-gnu/sane  or anything relevant in  /usr/local/lib  in either machine.
