>Description:
Some utility programs included with sane-backends fail to link
because they encounter multiple definitions of symbols found both
in system libraries and in a private library archive.  E.g.,

gcc -pipe -o .libs/scanimage scanimage.o stiff.o -framework CoreFoundation -framework IOKit  -L/Volumes/NetBSD/tmp/pkgsrc/graphics/sane-backends/work/.buildlink/lib ../lib/liblib.a ../backend/.libs/libsane.dylib /Volumes/NetBSD/tmp/pkgsrc/graphics/sane-backends/work/.buildlink/lib/libusb.dylib -lpthread -lm /Volumes/NetBSD/tmp/pkgsrc/graphics/sane-backends/work/.buildlink/lib/libjpeg.dylib
ld: multiple definitions of symbol _getopt
/usr/lib/libpthread.dylib(getopt.So) definition of _getopt
../lib/liblib.a(getopt.o) definition of _getopt in section (__TEXT,__text)
ld: multiple definitions of symbol _opterr
/usr/lib/libpthread.dylib(getopt.So) definition of _opterr
../lib/liblib.a(getopt.o) definition of _opterr in section (__DATA,__data)
ld: multiple definitions of symbol _optind
/usr/lib/libpthread.dylib(getopt.So) definition of _optind
../lib/liblib.a(getopt.o) definition of _optind in section (__DATA,__data)
ld: multiple definitions of symbol _optopt
/usr/lib/libpthread.dylib(getopt.So) definition of _optopt
../lib/liblib.a(getopt.o) definition of _optopt in section (__DATA,__data)
gnumake[1]: *** [scanimage] Error 1
gnumake: *** [all-recursive] Error 1
*** Error code 2

Stop.
bmake: stopped in /usr/pkgsrc/graphics/sane-backends


Attempting to change the Makefile of the offending targets to omit
the local library and use only the system library results in additional
symbols being undefined:

gcc -pipe -o .libs/scanimage scanimage.o stiff.o -framework CoreFoundation -framework IOKit  -L/Volumes/NetBSD/tmp/pkgsrc/graphics/sane-backends/work/.buildlink/lib ../backend/.libs/libsane.dylib /Volumes/NetBSD/tmp/pkgsrc/graphics/sane-backends/work/.buildlink/lib/libusb.dylib -lpthread -lm /Volumes/NetBSD/tmp/pkgsrc/graphics/sane-backends/work/.buildlink/lib/libjpeg.dylib
ld: Undefined symbols:
_getopt_long
_md5_buffer
gnumake[1]: *** [scanimage] Error 1
gnumake: *** [all-recursive] Error 1
*** Error code 2

Stop.
bmake: stopped in /usr/pkgsrc/graphics/sane-backends


>How-To-Repeat:
On MacOS 10.1.x or 10.2.x with developer tools installed:

cd .../pkgsrc/graphics/sane-backends
bmake


>Fix:
This is probably not the right way to do this, but I've worked around
the problem by commenting out the symbols in the private library
source file as follows:

cd .../pkgsrc/graphics/sane-backends
bmake configure
