[ ... looking through the log ... ]

They don't get deleted later.  The files to be installed don't get
created to begin with.  This is arguably a bug in the sane-backends
build system but you can easily work around it by running a `make`
before doing a `make install`.

It looks like the homebrew stuff assumes that `make install` will be
smart enough to also trigger builds for everything that needs to be
installed.  A bit overly optimistic, if you ask me ;-)

Below is the Makefile.am snippet that installs the configuration files.
The first line after the @list, checks for a readable configuration but
because all these files are generated they don't exist unless you run a
`make install` first.

          @# Libtool has a bug where it will sometimes symlink the last
          @# installed library in $(sanelibdir) to $(sanelibdir)/libsane.*.
          @# Having two libsane's can cause issues so get rid of it.
          -rm -f $(DESTDIR)$(sanelibdir)/libsane.*
          test -z "$(configdir)" || $(MKDIR_P) "$(DESTDIR)$(configdir)"
          test -z "$(configdir)/dll.d" || $(MKDIR_P) 
          @list="$(BACKEND_CONFS_ENABLED) saned.conf dll.conf"; for cfg in 
$$list; do \
            if test ! -r $${cfg}; then continue; fi; \
            if test -f $(DESTDIR)$(configdir)/$${cfg}; then \
            echo NOT overwriting $${cfg} in $(configdir)...; \
            else \
            echo installing $${cfg} in $(configdir)/$${cfg}...; \
            $(INSTALL_DATA) $${cfg} $(DESTDIR)$(configdir)/$${cfg} \
            || exit 1; \
            fi; \

I pushed a fix for this in 519ff57.

Hope this helps,
