The right fix would be that the glib people already did that :-)

It shouldn't, the library's name is libsane, but the "-l" is always
without the "lib". It seems to work with libsyslog and the other libs
so I have no idea why it doesn't work with SANE.

Maybe.

Maybe $sane_config_major_version is empty/not set? It's set above in

  sane_config_major_version=`$SANE_CONFIG $sane_config_args --version | \
    sed 's/\([[0-9]]*\).\([[0-9]]*\).\([[0-9]]*\)/\1/'`

Maybe add something like
  echo "sane_config_major_version is \"$sane_config_major_version\""
after this line to see what happens.

Maybe "gimp-tool"?
