I guess, its a conflict with using mutiple versions of Rake Gem.

If you have many applications, which require different rake gem versions to run..

Install RVM,

Do a rvm gemset create gemset\_name

and then place appropriate gem versions of rake and other gems in those project specific gemsets.. to avoid conflicts..
