SQLite3 hook up error on OS X 10.4.5

friends of the int-arweb.

what does this mean:

(in bold) ActiveRecord::StatementInvalid in Contact#create

SQLite3::SQLException: SQL logic error or missing database: INSERT
INTO contacts

Context:
this happened after I had finished setting up RoR as per the tutorial
at http://maczealots.com/tutorials/ruby-on-rails/

the database, is like, there. is there a nice ruby command like deal
to test if everything is hooked up correctly?

grough…
thanks,
