Rails revision 5186, activerecord broken ?

Hi,

I would like to submit a patch for ActiveRecord (Rails at revision 5186) but got confused when after the checkout of rails and running "rake in activerecord's folder.

I got 2 Errors and 1 Failure:

1) Error:
test_find_all_by_array_attribute(FinderTest):
ActiveRecord::StatementInvalid: Mysql::Error: ...

2) Failure:
test_native_decimal_insert_manual_vs_automatic(MigrationTest) ...

3) Error:
test_find_with_more_than_one_string_key(PrimaryKeysTest):
ActiveRecord::StatementInvalid: Mysql::Error: ...
