On a new machine, installed ruby with the 1-click installer for windows. Installed rails 2.3.2 and all associated gems, then I installed the sqlite3 binaries (into the c:\ruby\bin folder). Lastly I did gem install sqlite3-ruby -v=1.2.3 (which is apparently the latest version that works with windows)

This error happens when I run rake db:migrate or when any ActiveRecord object is touched at runtime.

The error looks like this:

** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:migrate
rake aborted!
**uninitialized constant Encoding**  <----

Any help resolving this error would be greatly appreciated!
