the libgphoto2_port/configure script checks for the function "usb_busses" in libusb ... but "usb_busses" is not a function, so on some systems/binutils, it fails. simple fix for our ebuild: sed -i s:usb_busses:usb_find_busses: libgphoto2_port/configure
I'll trade you the fix with some arm/sh/s390 gnome stabilizing! ;)
hopefully fixed, thanks for reporting. I'd really like to see some gnome packages get their stable keywords though...
