Redmine

Here is my environment:

----------------------------------------------------
lihuod@zebra-gateway:~/redmine-1.2$ ruby -v
ruby 1.8.7 (2010-01-10 patchlevel 249) [x86_64-linux]
-----------------------------------------------------
lihuod@zebra-gateway:~/redmine-1.2$ gem -v
1.3.7
-----------------------------------------------------
lihuod@zebra-gateway:~/rubygems-1.3.7$ gem list --local | grep rack
rack (1.1.2)
----------------------------------------------------
lihuod@zebra-gateway:~/rubygems-1.3.7$ gem list --local | grep rake
rake (0.9.2)
----------------------------------------------------
lihuod@zebra-gateway:~/rubygems-1.3.7$ gem list --local | grep i18n
i18n (0.4.2)
-----------------------------------------------------
lihuod@zebra-gateway:~/rubygems-1.3.7$ mysqld --version
mysqld  Ver 5.1.41-3ubuntu12.10 for debian-linux-gnu on x86_64 ((Ubuntu))

I follow the official intstructions, and get the errors and warnings:
