ODBC with Snow Leopard

Can someone please post or refer to detailed instructions for getting
Rails going on Snow Leopard with ODBC to a MS SQL server? The Rails
Wiki is pretty bad and I can't seem to get it going!

Thanks,
Tom

Here is some information for anyone else struggling with this:

Anyone else got any good resources to get this going?

Thanks!
Tom
