Notes on installing the door-controller
DO NOT FOLLOW THESE NOTES, THEY ARE HACKS!
Do not install node from apt, install v0.10.x (x = 28)
Use gpio-admin from pull request #6 romilly/quick2wire-gpio-admin#6
Make similar changes to pi-gpio node module
If you can't install bcrypt use
--unsafe-perm (or, you know, just fix the permissions)
