Can't compile the ROM on ArchLinux x86_64

Hello,

I've tried to compile Tuff.gb using the latest revision of the git repo and I get the following error

node convert src/data src/data/bin
module.js:339
    throw err;
    ^

Error: Cannot find module 'bluebird'

Yes, I have installed the bluebird module using npm install -g bluebird but it doesn't change a thing.
