Thanks to a previous post by Oliver Schwartz (http://www.mostang.com/pipermail/sane-devel/2002-May/003603.html) that my problem appears to be caused by a problem with the particular rpm. On upgrading some links don't get fixed. Uninstalling the RedHat package and then installing the 1.0.7 package from scrach appears to have fixed the problem. - Jost
