I tend to prefer using DBIC::Schema::Loader directly.  Here's an example:

use warnings;
use strict;
use DBIx::Class::Schema::Loader qw/ make_schema_at /;

                   components => ['InflateColumn::DateTime'],
                   debug => 1,
                   relationships => 1,
                   dump_directory => './lib' ,
               ["dbi:SQLite:dbname=db/meta.db", "",""]);

But the BEGIN block advice is also sound.  As far as using
EncodedColumn goes, I'd recommend having a look at
Catalyst::Helper::AuthDBIC for an example of how to achieve this with
Schema::Loader generated classes (although it doesn't use the BEGIN
trick because I didn't know about it).
