Unpacking gems in vendor - but what about dependent gems?

Let’s say, that I need the gem pdf-writer for a rails project. And I
define it inside environment.rb and run rake gems:unpack

No problem there, pdf-writer is installed into vender/gems.

But pdf-writer itself depends on some other gems like “color” and
“transaction-simple”. AND “color” depends on another gem “hoe”.

How do I get these gems unpacked into vendor/gems automatically?
