I haven't been able to use the "clear scr" command in a while, as I get the following error:

root@server:~# clear                                                     
The program 'clear' is currently not installed.  You can install it by typing:  
apt-get install ncurses-bin                                                     
bash: clear: command not found

root@server:~# apt-get install ncurses-bin

ncurses-bin is already the newest version.

I'm using Ubuntu Server 9.10.

I did some development with the ncurses library a while ago, so I've no doubt broken something.
