Contents missing when adding through npm
I have a project where I am using both Keyrune and [Mana](https://github.com/andrewgioia/Mana). I've added both to my package.json like this:

>  "dependencies": {
>    "keyrune": "git+https://git@github.com/andrewgioia/Keyrune.git",
>    "mana": "git+https://git@github.com/andrewgioia/Mana.git"
> }

When I do a npm install, both folders get created in my node_modules as expected. However, the Mana package comes out fine, while in the Keyrune package files are missing. The only files that are available are package.json and README.md. There are no css, fonts or less folders.
