problems installing Thalassa on Node 4.1 or higher?

[FabioSilvaBRZ]

I receive this message (and a lot of stack trace):
$ npm install thalassa -save
$ npm WARN engine hapi@1.8.3: wanted: {"node":"0.10.x"} (current: {"node":"4.1.2","npm":"2.14.4"})
When I have installed it as a server alone, no problem: I have used this version of Node 0.10.x.

But if I want to use Thalassa inside my app (Client as an Embedded Module) I cannot conciliate the Node versions for both the app and Thalassa. Is there a way to 'update' the hapi?
