Font Conflicts From Snow Leopard

Anyone else experience font conflicts after upgrading to Mac OS X Snow Leopard? I didn’t realize I had issues until trying to read the install instructions for YOURLS. Here’s a screen shot of what it looks for me.

I was like this must be some developer code or something. But copying and pasting the instructions gives me a readable view:

1. Unzip the YOURLS archive
2. Copy includes/config-sample.php to includes/config.php
3. Open includes/config.php with a raw text editor (like Notepad) and fill in the required settings
4. Upload the unzipped files to your domain public_html or www folder
5. Create a new database (see Configuration – you can also use an existing one)
6. Point your browser to http://yoursite.com/admin/install.php

Opening Fontbook, I have a ton of duplicate fonts being reported. I think that once I resolve all these dupes, things will display normally again.
