Subject: Re: ONLamp tutorial install issue (mysql gem)

You don't need to install the MySQL gem at all (at least not for going
through the tutorial). Rails comes with a pure-Ruby interface to MySQL
that works just find for development (and even low volume production).
The gem just gives you a faster C-based version of the driver.

Also, you might want to consider trying Instant Rails and its "port"
of the ONLamp tutorial to be Instant Rails specific:
