file to import not found or unreadable: compass/css3 - ruby

Question

I have looked at the answers below and even after running compass compile I still get the error below.
I have installed all required gems but I keep getting the error.
What would be the best way to import fonts using the SASS workflow, any guidance would be greatly appreciated.
My Config.rb file
add_import_path "bower_components/foundation/scss"
http_path = "/"
css_dir = "css"
sass_dir = "sass"
images_dir = "img"
javascripts_dir = "js"
output_style = :compressed
My Gruntfile
/*jslint node: true */
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
sass: {
options: {
includePaths: ['bower_components/foundation/scss']
},
dist: {
options: {
outputStyle: 'compressed',
sourceMap: false,
},
files: {
'css/app.css': 'sass/app.scss'
}
}
}, // sass
compass: {
dev: {
options: {
config: 'config.rb'
}
} // dev
}, //compass
watch: {
options: {
livereload: true,
dateFormat: function(time) {
grunt.log.writeln('The watch finished in ' + time + 'ms at ' + (new Date()).toString());
grunt.log.writeln('Waiting for more changes...');
} //date format function
}, //options
scripts: {
files: ['*.js']
}, // scripts
//Live Reload of SASS
sass: {
files: 'sass/**/*.scss',
tasks: ['sass']
}, //sass
css: {
files: ['sass/*.scss'],
tasks: ['compass']
},
html: {
files: ['*.html']
}
} //watch
});
grunt.loadNpmTasks('grunt-sass');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-compass');
grunt.registerTask('build', ['sass', 'compass']);
grunt.registerTask('default', ['build', 'watch']);
}
