Cannot read property 'MeteorX' of undefined on *.meteor.com

[Abigail Watson]

Hi!
Just a quick update. I tried to deploy an app this morning to *.meteor.com using socialize:base-model, and got a broken site and the following errors in the client console (server console was fine).

Uncaught TypeError: Cannot read property 'MeteorX' of undefined(anonymous function)
Uncaught TypeError: Cannot read property 'ServiceConfiguration' of undefined(anonymous function) 
Uncaught ReferenceError: Spacebars is not defined

The meteorhacks:unblock and meteorhacks:meteorx dependencies seem to be causing a fuss. fyi.

you can see this issue to find out your problem.
meteorhacks/meteorx#5

This should no longer be an issue as publications have been removed in favor of choice of join package and the unblock package has been removed from the deps
