[Catalyst] crud example not working

Something IS missing - the 'Addresses.pm' module!  Actually, I'd be 
surprised if it's actually missing, however Perl can't find it for some 
reason.  I would check the 'package' declaration in your module against 
the error.  It could be an issue with plurality, likely because a change 
was made somewhere along the line in how DBIC handles this.  Whatever 
the case, perl is looking for that module and can't find it.
