[SOLVED] File to import not found or unreadable: susy

File to import not found or unreadable: susy

I just can't figure out what is wrong with my setup with Susy. I am on OS X 10.7.4

I have followed along here: http://susy.oddbird.net/guides/getting-started/

Error

Syntax error: File to import not found or unreadable: susy.

My installed Gems:

*** LOCAL GEMS ***

chunky_png (1.2.6, 1.2.5)
compass (0.12.2, 0.11.7)
compass-boilerplate-plugin (0.1.0)

susy (1.0.3)

My config.rb file which is sitting in the root of the project

require 'susy' 
# Require any additional compass plugins here.

# Set this to the root of your project when deployed:
http_path = "/"
css_dir = "stylesheets"
sass_dir = "sass"
images_dir = "images"
javascripts_dir = "javascripts"

# You can select your preferred output style here (can be overridden via the command line):
# output_style = :expanded or :nested or :compact or :compressed

# To enable relative paths to assets via compass helper functions. Uncomment:
relative_assets = true

_base.scss

// ---------------------------------------------------------------------------
// Imports
@import "susy";

/* GRID SETUP
----------------------------------------------------------------------------------*/

$total-columns  : 12;
$column-width   : 4em;
$gutter-width   : 1em;
$grid-padding   : $gutter-width;
$show-grid-backgrounds  : true;
/* SECTION
----------------------------------------------------------------------------------*/

screen.scss

 @import "base";
 .container {
  @include container;
  @include susy-grid-background;
 }

I ran this command from the directory wpsvntree: compass create trunk -r susy -u susy with success.

then compass watch trunk/

Viewing my project I see the first above error.

I can't see where I have gone wrong.

Thanks.
