Rake migrate unintialized const dependencies

Hi,

I’m a ruby and rails newbie…
I am trying to get a 3rd party module running - Community Engine(which
requires Rails 2.3.4 )- because it seems like it does most of what I
need my project to do and I thought I could just extend it.

I am stuck at the point of doing rak db:migrate
I keep getting an uninitialized constant dependencies …

C:\projects\commanddo>rake db:migrate --trace > c:\temp\db_migrate.txt
rake aborted!
uninitialized constant Dependencies
