Can't start meteor without a working mongo connection

[thani-sh]

When meteorx is installed, the application will not start unless there's a working mongodb connection. Application crashes with error.

 Error: MONGO_URL must be set in environment

Same for me.
Does anybody have any clue or even a plan on how support MongoDB less applications?
