Rails - Jun 2011 - `exec': wrong number of arguments (ArgumentError) when using bundle exec

Hi! I''m trying to make a migration, but when I do "rake
db:migrate" tell me
this:

You have already activated rake 0.9.2, but your Gemfile requires rake 0.8.7. 
Consider using bundle exec.

Then, I use a bundle exec, but I have other error:

`exec'': wrong number of arguments (ArgumentError)
from /usr/lib/ruby/gems/1.8/gems/bundler-1.0.15/lib/bundler/cli.rb:346:in 
`exec''
from

from /usr/lib/ruby/gems/1.8/gems/bundler-1.0.15/bin/bundle:13
from /usr/bin/bundle:19:in `load''
from /usr/bin/bundle:19

Anyone know why show me this error?

When it says try using bundle exec... it means that you have to prefix the 
command with that
Use it like this ''bundle exec rake db:migrate''
