[SLUG] No space left on device ....***@@@!!!

[Adam Bogacki <adam@xxxxxxxxxxx>]

Hi,
	I somewhat over-enthusiastically downloaded
packages onto my spanking new Woody 3.0 unstable install 
and now have ...
----------------------------------------------------------
# df
Filesystem                               use% mounted on
/dev/hdb5                                11%  /
/dev/hdb2                                39%  /boot
/dev/hdb9                                 1%  /home
/dev/hdb6		                100%  /usr
/dev/hdb7                                15%  /usr/local
/dev/hdb8                                48%  /var
/dev/hde5                                17%  /home/cyberia
/dev/hde6                                16%  /usr/cyberia
-----------------------------------------------------------------
... giving me the message "no room left on device" when
apt or aptitude try to install upgrades in /usr ...

Is there an easy way to purge, or remove, unused packages ?
