Eyeglass with Gulp Sass

gulpfile.js

var gulp = require('gulp'),
   sass = require('gulp-sass'),
   Eyeglass = require('eyeglass');
   
gulp.task('sass', function () {
   gulp.src('sass/**/*.scss')
      .pipe(sass(new Eyeglass({
         // Sass options go here
      })))
      .pipe(/* Other Stuff */)
})

It doesn't seem to work (anymore?):

TypeError: object is not a function

for new Eyeglass(...)

Using node version v0.12.7,
installed dependencies using command

npm install --save-dev gulp gulp-sass eyeglass

With best regards

This works for me:
