At least about a year ago, I could build sane-backends on OpenBSD
without any changes (and I could actually scan something). As far as I
know, nothing has changed in sane-backends concerning library loading
since then.

Maybe a change in libtool? Do you use the libtool that comes with SANE
or a different one?

Which was the last version of sane-backends that worked?

There is a now commented out part in the install traget of
backend/Makefile.in that was used for creating links. However, it
hasn't been used since 2 years:

The dll backend looks for *.so.1 as far as I can see.

The symlinking should be done by libtool.

scanimage itsself doesn't llok for any backends. Usually it's linked
statically or linked to the shared libsane-dll backend. The dll
backend then loads dynamically the other backends.
