Yeap - you double your trouble ;)

you need to configure that correctly before building the libs.
First cleanup everything in the sane-backends directory:

make distclean

then continue with the configure step:

./configure --prefix=/usr --sysconfdir=/etc --mandir=/usr/share/man --infodir=/usr/share/info --with-lockdir=/var/lock/sane


make all
make install

that should override the existing stuff.

That's okay, but when the wrong (means old) backend is used, the option
has no effect, at least the file, where you've changed, will not be used.

Yes. Adjust the installation paths, see above.
