Unfortunately, I was in a rush to get it done and didn't take notes. I 
do remember now that the true type fonts were not installed on the 
machine either so I copied one over from a windows machine. Here's a 
list of pear stuff installed:

Installed packages, channel pear.php.net:
=========================================
Package        Version   State
Archive_Tar    1.3.1     stable
Console_Getopt 1.2       stable
Image_Text     0.6.0beta beta
PEAR           1.4.9     stable
Text_CAPTCHA   0.3.1     alpha
Text_Figlet    1.0.0     stable
Text_Password  1.1.0     stable
XML_RPC        1.4.8     stable

Here's  a snippet of code that works (for me):

<?php

require_once 'Text/CAPTCHA.php';
session_start();

$captcha = Text_CAPTCHA::factory('Image');
$options = array('font_size'=>'20',
        'font_path'=>'/home/webdir/',
        'font_file'=>'VERDANA.TTF');
$captcha->init(150, 60,NULL,$options);
$image = $captcha->getCAPTCHAAsJPEG();
file_put_contents('captcha.jpg', $image);
$_SESSION['captcha_phrase'] = $captcha->getPhrase();

?>

The captcha has succeeded in stopping any futher spam from hitting my 
clients comment board. I've read, however, that something as simple as a 
fixed image and a request to retype the displayed word is sufficient
