PHP Fatal error: Cannot redeclare class freepbx_conf while trying to install FreePBX Framework

Hopefully somebody has seen this before. I am using FreePBX 2.10, which I just downloaded a few days ago. I was attempting to install FreePBX Framework from the Module Administration app.

The installation gives this output and then stops:

installing files to /var/www/html…done
installing files to /var/lib/asterisk/bin…done
installing files to /var/lib/asterisk/agi-bin…done
Checking for upgrades…1 found
Upgrading to 2.10.1…
-> Running PHP script /var/www/html/admin/modules/framework/upgrades//2.10.1/migration.php

When I check httpd-error log I see:

[Thu Jul 18 12:24:41 2013] [error] [client 192.168.10.11] PHP Fatal error: Cannot redeclare class freepbx_conf in /var/www/html/admin/libraries/freepbx_conf.class.php on line 50, referer: https://asterisk.internal.dev.domain.com/admin/config.php

Hopefully this is something I can easily fix? Let me know if additional information would be useful. Thanks!
