I am trying to upgrade to 4.4 from ...perhaps it was 3.2.8? Anyway, this is on one site of a Wordpress MU 3.8.1 installation that is otherwise completely functional.  We're running  MySQL 5.5.34, PHP 5.5

I now have an error when trying to get to the upgrade page at (My-site.com/wp-admin/admin.php?page=CiviCRM&q=civicrm/upgrade&reset=1):
 
Warning: require_once(CRM/Core/ClassLoader.php): failed to open stream: No such file or directory in /webroot/my-path/wp-content/plugins/civicrm/civicrm.settings.php on line 299 Fatal error: require_once():

Failed opening required 'CRM/Core/ClassLoader.php' (include_path='.:/webroot/my-path/wp-content/plugins/civicrm/civicrm/:/webroot/my-path/wp-content/plugins/civicrm/civicrm//packages:.:/usr/share/pear:/usr/share/php53/pear') in /webroot/my-path/wp-content/plugins/civicrm/civicrm.settings.php on line 299
I haven't found much help via searching this error and don't understand the syntax of the error string - any advice?   

Edit -- I do not find usr/share/pear or usr/php53/pear in the file directory using a path search in filezilla - I assume this is the problem? 

I also marked out the lines calling for the classloader.php (299 & 300 in civicrm.settings.php as well as the same lines in civicrm.php (318ish)  This leads to a different error (essentially that it cant find the classloader.php - but it fails more gracefully!

I can regress PHP to 5.4 if needed- This was a recent shift from 5.3.2 with the update to 3.8.1 and civicrm update.

Did you fully remove the previous source before installing the new code?

I followed the instructions here https://wiki.civicrm.org/confluence/display/CRMDOC/Upgrade+WordPress+Sites+to+4.4 including a complete deletion of the civicrm plugin folder.

I double checked the paths in civicrm.settings.php - only the template_c path was odd - but should apparently be generated if needed.  Everything else seems to match up. 

These paths in the error could not be found anywhere I looked in my entire directory tree however.  Where are these typically?
/usr/share/pear:/usr/share/php53/pear'

There was another error when I had google analyticator plug in activated, but of course, after deactivating it, it disappeared.
