Ruby odbc

Hi all!

I am trying to use ActiveRecord migrations from Linux on an MS SQL
Server database running on windows. I am following the instructions
given in

I have successfully set up freetds and unixODBC, and I can connect fine
using tsql and isql.

When I try connecting using ruby I get the following:

[root@pippin laptop_scripts]# irb
irb(main):001:0> require ‘odbc’
=> true
irb(main):002:0> require ‘dbi’
=> true
irb(main):003:0> dbh = DBI.connect(‘dbi:ODBC:database_name’, ‘username’,
NoMethodError: undefined method default_attributes' for #<ODBC::Driver:0xb7f6ade4 @attrs={}, @name=nil> from /usr/lib/ruby/site_ruby/1.8/dbi.rb:420:in connect’
from /usr/lib/ruby/site_ruby/1.8/dbi.rb:215:in `connect’
from (irb):3

Checking the ruby odbc documentation, the default_attributes method is
not defined, and the Driver class inherits from Object.

dbi.rb also tries to call a “connect” method on the Driver class, but
“connect” is only defined on the ODBC module, not the Driver class.

What do I need to do to be able to connect? Any help is greatly
