Another poster has suggested how to clean this up, but if you want to keep
such things from happening in the first place, edit (or create)
/etc/apt/apt.conf and put the following line in it:

   Aptitude::Purge-Unused "true";

>From then on, whenever a package is removed because it was
automatically installed and is no longer needed as a prerequisite for
something else, it will also be purged.  That works for commands like
"aptitude full-upgrade" and "aptitude safe-upgrade".  I'm not sure
if it will have any affect with apt-get or synaptic.
