Rails - Aug 2006 - Connecting to multiple databases, mysql win32 gem problem

I am trying to connect to multiple databases, and have setup an abstract class
with a call to establish_connection:

class TestBase < ActiveRecord::Base
   self.abstract_class = true
end

TestBase.establish_connection(
      :adapter  => "mysql",
      :host     => "host",
      :username => "user",
      :password => "pass",
      :database => "db"
)

class Table < TestBase
...
end

I get an error when trying to use the new connection:
Mysql::Error: Lost connection to MySQL server during query:



So, I installed the mysql win32 gem:
gem install mysql


and now I get an error on any page, 
undefined method `each'' for #<Mysql:0x3883f08>


Has anyone figured out how to fix this (besides uninstalling the gem)?
