I only manage to reproduce something remotely similar when I put a HAVE_GPHOTO2="false" in my environment, but even then the log is not the same. Can you please attach the complete build log (not just the part before the error) and tell me the output of: pkg-config --modversion --libs libgphoto2 as well as the output of "emerge -pv sane-backends"? Thank you!

Could you please re-install libgphoto2?
(In reply to comment #7) > Could you please re-install libgphoto2? Alas, it didn't help.
pkg-config still does not know anything about it?
Same happened here. No idea how it got there, but /usr/lib/pkgconfig/libgphoto2.pc has a comma at the end of line 12 that doesn't seem to belong there: prefix=/usr exec_prefix=${prefix} libdir=${exec_prefix}/lib includedir=${prefix}/include VERSION=2.4.6 driverdir=${libdir}/libgphoto2/2.4.6 Name: libgphoto2 Description: Library for easy access to digital cameras URL: http://gphoto.org/proj/libgphoto2/ Version: 2.4.6 Requires: libgphoto2_port >= 0.6.2, Libs: -L${libdir} -lgphoto2 -lm Cflags: -I${includedir}/gphoto2 Deleted it, pkg-config now has meaningful output again, and sane-backends builds, too.
Maybe the libgphoto2 maintainers are interested in this...
Erm looks like we have a long standing undercover bug: # Fix pkgconfig file when USE="-exif" if use exif; then sed -i "s/, @REQUIREMENTS_FOR_LIBEXIF@//" libgphoto2.pc.in || die " libgphoto2.pc sed failed" fi -> try to put a ! before use exif and rebuild libgphoto2, that should fix the problem.
Same error here. Taking the comma off of /usr/lib/pkgconfig/libgphoto2.pc fixed it. W

Good catch, Gilles. Fixed without a bump.
(And fixed...)
