CLI initial message not being displayed

It seems trivial, but on an Asterisk 1.8.3.2 box, the usual message that’s displayed on starting the CLI with
asterisk -r doesn’t display:

"Asterisk version, Copyright © 1999 - 2010 Digium, Inc. and others.

That doesn’t display. All I get is “Verbosity is at least 3”. Nothing more.

What could be causing this?
