I think I've managed to work around the sane-backends problem I mentioned
yesterday.

Workaround:  Edit

    graphics/sane-backends/work/sane-backends-1.0.12/lib/getopt.c

and comment out:

    global vars:  opterr, optind, optopt.
    function:     getopt

Or the patch, as follows:

With the above modifications in place, sane-backends builds and installs.
The 'test' driver works, at least.  I am still working on installing on
a machine that has a scanner attached.

(I'm anticipating shared-library problems.  During installation, I saw
a number of command lines go by refering to "*.so" files, rather than
"*.dylib" files...)
