Rails - Jun 2006 - help... can''t run ActiveRecord unit tests to test bug fix

I found a bug in ActiveRecord. Being a good netizen, I thought I  
would write a test to illustrate the bug, fix it, and then submit a  
patch to the maintainers.

However, I can''t run the AR tests. I followed the instructions in  
RUNNING_UNIT_TESTS but it generates an error immediately

/opt/local/lib/ruby/gems/1.8/gems/activerecord-1.14.2/test cremes$  
ruby -I "connections/native_mysql" active_schema_mysql.rb
./../lib/active_record/base.rb:246: undefined method `cattr_accessor''  
for ActiveRecord::Base:Class (NoMethodError)
         from /opt/local/lib/ruby/site_ruby/1.8/rubygems/ 
custom_require.rb:21:in `require''
         from ./../lib/active_record.rb:37
         from ./abstract_unit.rb:5
         from active_schema_mysql.rb:1

It can''t seem to find the definition for #cattr_accessor which is  
defined in the activesupport gem.

This is Rails 1.1.2 comprised of AR 1.14.2, ActiveSupport 1.3.1, etc.  
running on OSX 10.4.6 & Ruby 1.8.4 from darwinports.

Any ideas how to get this working?

BTW, the bug in AR is in the #add_column/#drop_column methods.  
Currently it isn''t handling reserved words correctly if one is used  
as a column name.

Example Migration:
self.up
   drop_column :some_table, :condition
end

MySQL allows the use of reserved words as column names provided they  
are quoted using the backtick. This is actually handled properly  
elsewhere in AR via the #quote_column_name method (in  
mysql_adapter.rb), but this method isn''t used in #add_column or  
#drop_column.
