I get "couldn't find file handlebars.runtime" error inside a rails engine

[Allanon29]

I really like the idea of this gem, but when I require it in application.js ( inside a rails engine ) I get this error:
"couldn't find file handlebars.runtime"

This happens with handlebars.runtime and handlebars also.
I also tried to require it like this:
engine_name/handlebars.runtime

but the same error occurs.

Any suggestions to solve this?

I have the same issue. It does not seem like the gem's assets are being pumped into the asset pipeline. Do we need to run a generator in order to have the handlebars javascript files put in the proper place?
