commit 0d619dde071d072d401a2a804f5c5f88fb3abe43
Author: Francois Gouget <fgouget@free.fr>

    check: sane-devel is only needed at compile time.
    
    sane-devel provides sane-config which is used to show the sane version.
    However there is no minimum version requirement so that sane-devel is
    not really required at runtime.
