I'm getting this error when I try to run my upgrade script (http://localhost/civicrm/upgrade?reset=1):

Fatal error: Cannot redeclare class DB_Error in /Users/ken/Documents/SIA/site-upgrade/sites/all/modules/civicrm/packages/DB.php on line 983

Any hints on what could be going on?  I'm using:

Drupal 7.31
MySQL 5.5.21
PHP 5.4.24

I see that 4.5.1 is released now, is it likely to fix this problem?  I'm still not clear on what went wrong.

I'm revisiting this thread - I had to give up last time, but I'm trying again (this time upgrading from 4.4.11 to 4.5.5, though) and I still get the same error.

I'd like to look in the logs, but no logs seem to be written - all the files in sites/default/files/civicrm/ConfigAndLog are pretty old, and I'm not sure how to get them written.  Any tips on why no logs are happening?
