My fault -- I didn't set up namespaces correctly in the class, and I hadn't noticed because I'm unable to test the Unicorn driver from here.
I've just pushed a fix to master -- you should be able to pull it down, or you can make the change manually based on this diff:
Obviously this means you're the first person to try out the Unicorn driver... so please let me know if you run into any other problems.

Subject: [VuFind-Tech] VuFind 2 and Symphony with Unicorn Driver
I am currently trying to use the Unicorn Driver,
However after selecting it, and changing the driver link, I am getting the following error: [Fri Oct 12 11:58:06 2012] [error] [client 22.214.171.124] PHP Fatal error: Class 'VuFind\\ILS\\Driver\\ConnectionManager' not found in /usr/local/vufind2/module/VuFind/src/VuFind/ILS/Driver/Unicorn.php
Line 83 is: $this->db = ConnectionManager::connectToIndex();
Any ideas of what might be causing this and how to fix it.
