SANE's dynamic loading mechanism looks for configs in SANE_CONFIG_DIR, and the libraries are expected to be either in LD_LIBRARY_PATH or in the LIBDIR, which is set during the build to $PREFIX/lib/sane. A small patch is necessary to make SANE respect backend search paths set by Guix. * gnu/local.mk: Register sane-look-for-plugins-in-SANE_BACKEND_LIB_PATH.patch * gnu/packages/scanner.scm (sane-backends-minimal): Patch dynamic loading mechanism to look for libraries in SANE_BACKEND_LIB_PATH.
