I'm not sure this is a matter of sticking with outdated software. This software gets installed as part of the Solaris 10 system and users like myself may not know why. We don't use it directly in our work but does any part of Solaris need it? If I removed it would anything break? If I knew it was safe to remove, i'd remove it. It isn't always clear what dependencies the system may have on outdated software packages such as these.
