Thanks for everyones input. Here's the final (clean) solution to my problem for the benefit of others:
1) We need the x86_64 versions of libusb-devel and libieee1284-devel - to install these on Fedora 8: yum erase libieee1284-devel libusb-devel yum install libieee1284-devel libusb-devel Be careful that the "yum erase" line doesn't erase other dependencies and make sure to reinstall them if it does! 2) Run the sane-backends configure script with the LDFLAGS option to point to the lib64 directory: ./configure LDFLAGS=-L/usr/lib64 3) You can now "make" and "make install" as required Enjoy.
