--- Comment #6 from Rosanne DiMesio dimesio@earthlink.net --- This was not changed in our build scripts. The Required dependencies are generated automatically by dpkg-shlibdeps during the packaging process. There were multiple patches affecting sane that went into 6.21, and apparently one or more of those changes caused dpkg-shlibdeps to start treating it as required.
