Rake Aborted - Error Message Suggests Fix, Epic Fail

I'm running through the Depot tutorial on Agile Development w/ Rails
(2nd Edition). I've created a DB and connect to it (and create dummy
tables) via terminal with no problem. Everything is cool up until page
72 where I'm asked to run a Rake migration from the command line:

rake db:migrate

returns:

rake aborted!
Please install the msql adapter: `gem install activerecord-msql-
adapter` (no such file to load -- active_record/connection_adapters/
msql_adapter)

If I take the suggestion and type:

gem install activerecord-msql-adapter

returns:

ERROR: could not find activerecord-msql-adapter locally or in a
repository

Running the migration with --trace returns:

(in /Users/chad/src/ruby/depot)
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!
Please install the msql adapter: `gem install activerecord-msql-
adapter` (no such file to load -- active_record/connection_adapters/
msql_adapter)

Anyone have any ideas?

Thanks in advance,

Looks like you typed msql instead of mysql in your database.yml

Fred

Yes - that was it. Thanks man.
