Install mongoskin with native options (using npm)

When I install mongoskin using npm, it tells me:

To install with C++ bson parser do <npm install mongodb --mongodb:native>

This is fine when doing installing manually.

Supposed I want to add mongoskin as a dependency to my package.json file - how do I then specify this option? Of course I can include something such as

"dependencies": { "mongoskin": "*" }

but where do I provide the --mongodb:native parameter?
