Gotcha! :D
Fonts directory was misdefined - I did not use any kind of symlinking, 
just copied everything to my virtual server and of course missed this 
definition in render.php - this directory should imho be defined in 
config.php, not every install is identical, and I am quite certain this 
will pop up as a problem in future too.

Here is what I changed:

     // Render a captcha image and store the hash.  See register.tpl.
     $hash = generateCaptcha("./fonts/FreeSans.ttf", 6);

Call to generateCaptha now has proper directory and everything seems to 
be in working order to proceed.... hopefully

Thanks for your help! Now.. back to implementing authentication to 
various projects I'm working on... ;)
