Your db username or password is wrong, your MySql server is not
started, or you haven't created the database
This has nothing to do with Rails - I suspect you went throught the
environment setup part of the tutorial a bit too quickly.
You may also want to read up on netiquette. The Rails mailing list is

answer questions. Making snide comments about a framework a whole lot
of people feel passionately good about will not help your getting
meaningful answers. Just tone it down.
