Undefined method fetch when doing rake db:rollback

[mbillard]

It happens every time I try to rollback, no matter the content of the migration (even an empy migration).

Full stack trace below:

$ r db:rollback --trace
** Invoke db:rollback (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:rollback

An error has occurred, all later migrations canceled:

workaround to uncomment... bundle and run again. :-(
