Typos and Rails 3.0.4

[t7y]

Just to point out that there is a typo in the create_item migration file. It should be:
t.string :name
Rather than 'nome'.

On another note, I upgraded the version of Rails to 3.0.4, and the migration wouldn't run on the sharded database.
The following is my version of the Gemfile:

Please help me in resolving this issue. Thanks in advance,
Jerry
