Problem with RTx-Shredder and local hacks post-3.8.10 upgrade

Since upgrading to 3.8.10 from 3.8.9, rt-shredder returns:

Couldn’t find plugin 'Tickets’
Plugins list:
Objects
Users
Attachments
Summary
Tickets
SQLDump

Also, it appears that some local hacks we’ve installed under
rt-root/local (User_Overlay and Auth) no longer are being executed.

We’re running RT on RedHat Enterprise Server 5.6, Perl 5.12.3 (a
stand-alone install, not system-installed Perl), and MySQL 5.0.77.

User_Overlay.pm would clobber the internal RT’s User_Overlay.pm
Local hacks really want to live in User_Local.pm
