Rails 3.1.1 Indexer problem?

[kjudge]

Wanted to give this gem a try to tune up my queries, but I get the following error:

White-Dome:server kevin$ rake db:index_migration
/Users/kevin/.rvm/gems/ruby-1.9.2-p136/gems/rails-indexes-0.0.1/lib/rails-indexes/indexer.rb:332: warning: else without rescue is useless
rake aborted!
Don't know how to build task 'db:index_migration'

(See full trace by running task with --trace)
White-Dome:server kevin$ bundle exec rake -T db
/Users/kevin/.rvm/gems/ruby-1.9.2-p136/gems/rails-indexes-0.0.1/lib/rails-indexes/indexer.rb:332: warning: else without rescue is useless
rake db:create # Create the database from config/database.yml for the current Rails.env (use db:create:all to create all dbs in the config)
rake db:drop # Drops the database for the current Rails.env (use db:drop:all to drop all databases)
rake db:fixtures:load # Load fixtures into the current environment's database.
rake db:migrate # Migrate the database (options: VERSION=x, VERBOSE=false).
rake db:migrate:status # Display status of migrations
rake db:rollback # Rolls the schema back to the previous version (specify steps w/ STEP=n).
rake db:schema:dump # Create a db/schema.rb file that can be portably used against any DB supported by AR
rake db:schema:load # Load a schema.rb file into the database
rake db:seed # Load the seed data from db/seeds.rb
rake db:setup # Create the database, load the schema, and initialize with the seed data (use db:reset to also drop the db first)
rake db:structure:dump # Dump the database structure to an SQL file
rake db:version # Retrieves the current schema version number
