Try using schema:load and let us know if the problem persists. Generally it is less error prone than db:migrate when installing for the first time.

rake db:schema:load

[dcvezzani]

I have the same problem.

If I do run rake db:schema:load as suggested and then fire up my server, I get this:

ActiveRecord::StatementInvalid (PG::Error: ERROR:  relation "site_settings" does not exist
LINE 1: SELECT  "site_settings".* FROM "site_settings" WHERE "site_s...
                                       ^

'site_settings' wasn't in db/schema.rb, so it didn't get generated. More importantly, there are references to FileShare::Engine in other parts of the code:

find . -exec grep -l FileShare {} \;
./app/controllers/application_controller.rb
./app/helpers/file_share/application_helper.rb
./db/migrate/20101202170830_file_share_schema_after_create_file_attachments.rb
./db/migrate/20101202170831_file_share_seed.rb
./lib/tasks/file_share.rake
./log/development.log

I'm not sure at this point how vital FileShare is to the app, but I'm going to guard the migration in the same way 'file_share.rake' does:

if defined? FileShare::Engine
  ...
