[Catalyst] update_or_create problem with Catalyst::Engine::Apache::MP13 and DBIC

I appreciate the response.  The app is mounting the same perl5 tree from
an NFS-mounted filesystem, so I'm pretty sure that all the module
versions are the same.  And Apache::DBI isn't loaded.  The only
difference I can see is that the standalone server doesn't seem to use
DBIx::Class::Storage.  I'll give the other list a try.
