Just tried to reproduce this.  Configured 1.0.19 and the CVS snapshot
of 2009-02-26 with --prefix=/tmp/sane, built and installed.
Installing the snapshot over 1.0.19 results in:

  -rwxr-xr-x 1 olaf olaf    875 2009-02-27 10:21 libsane-fujitsu.la
  lrwxrwxrwx 1 olaf olaf     24 2009-02-27 10:21 libsane-fujitsu.so -> libsane-fujitsu.so.1.1.0
  lrwxrwxrwx 1 olaf olaf     24 2009-02-27 10:21 libsane-fujitsu.so.1 -> libsane-fujitsu.so.1.1.0
  -rwxr-xr-x 1 olaf olaf 244142 2009-02-27 10:18 libsane-fujitsu.so.1.0.19
  -rwxr-xr-x 1 olaf olaf 296770 2009-02-27 10:21 libsane-fujitsu.so.1.1.0

for all backends from the snapshot that were built.  Re-installing
1.0.19 on top of that gives:

  -rwxr-xr-x 1 olaf olaf   1013 2009-02-27 10:23 libsane-fujitsu.la
  lrwxrwxrwx 1 olaf olaf     25 2009-02-27 10:23 libsane-fujitsu.so -> libsane-fujitsu.so.1.0.19
  lrwxrwxrwx 1 olaf olaf     24 2009-02-27 10:23 libsane-fujitsu.so.1 -> libsane-fujitsu.so.1.1.0
  -rwxr-xr-x 1 olaf olaf 244142 2009-02-27 10:23 libsane-fujitsu.so.1.0.19
  -rwxr-xr-x 1 olaf olaf 296770 2009-02-27 10:21 libsane-fujitsu.so.1.1.0

Repeatedly installing one version over the other does not cause any
differences in the above.

I've also tried installing the snapshot after I wiped all the links with

  find /tmp/sane/lib/sane -type l | xargs rm

but that resulted in the first list, i.e. all symlinks pointing to the
snapshot's backends.

Allan: Could you provide a log of `make install -C backends` _after_
       you remove the '--silent' option from the libtool invocation?

Chris: While still hacking on the build system, please don't turn off
       command echoing and command output.  We can do that once we're
       past the growing pains.

Hope this helps,
