Worried, ran yum -y update expecting to get the bind update but am
concerned as to why the following instant messaging packages were
installed as dependencies.  All of the following are instant messaging
related except cyrus-sasl.

Jul 30 17:00:49 Installed: cyrus-sasl-md5-2.1.22-4.i386
Jul 30 17:00:49 Installed: meanwhile-1.0.2-5.el5.i386
Jul 30 17:00:50 Installed: libsilc-1.0.2-2.fc6.i386
Jul 30 17:00:54 Installed: libpurple-2.5.5-3.el5.i386
Jul 30 17:00:58 Installed: libpurple-perl-2.5.5-3.el5.i386

Did anybody else notice the install of im clients on practically
headless non-gui systems?
Any explanation?
