Well, configure of sane-backends already prints a warning, if there is
a SANE installation at a different prefix. If this doesn't work, we
should fix it. Further more, it's stated in man sane, that you should
check, if another installation is there.

I don't think that frontends should make any assumptions on
backend-related stuff, e.g. check for dll.conf. And sometimes having
installed several versions in different places is intentional. I don't
want a warning in this case with every call of scanimage or
sane-find-scanner.
