I could recommend two modern options:
- Standalone PHP Link Directory or
- Mosets Tree on Joomla..
I used both, moved after after using both of them to Mosets Tree, it is more flexible and you get all Joomla nice things which are missing in PHPLd, especially about themes, articles, many plugins and modules to make your directory really reach..
