Sane is implemented in FC4/x86_64 with one x86_64 frontend and two (i386 and x86_64) backends. I guess the i386 backends are there to interface to i386 only frontends and the x86_64 backends interface xsane and scanimage.
My problem with this approch is that I need to upgrade sane-backends to the latest level which I would normally do by compiling them according to the instructions found on the sane projects web pages. However, such compilations will only affect the i386 elements and therefore I'll not have the upgrade I thought. Does anybody know how I should compile the x86_64 version? The sane-project doesn't know and refer to the Fedora team packagers who apparently have done it all by themselves.
Would a decent circumvention be to erase the sane packages from the system and compile new ones to an i386 platform or will that not work?
