Can't load SPI cape

[RudyJM]

Can't load ADAFRUIT-SPI0 using b.loadCape('ADAFRUIT-SPI0');

This is all I have in my node js file (test.js) var b = require('octalbonescript');

console.log('unload hdmi cape'); b.unloadCape('cape-univ-hdmi');

console.log('load spi cape') b.loadCape('ADAFRUIT-SPI0');

console.log('done!')

Running the latest version of Debian Jessie for the BBB
