<nitpick>
That is open for discussion.  You can install iscan under /usr/local
and create a symbolic link to the epkowa backend in /usr/lib/sane or
set up your LD_LIBRARY_PATH to include /usr/local/lib/sane.  It's not
so much iscan's fault as that the distribution's SANE packages assume
all backends live in the same place.
