[racket] how to get tests/eli-tester in jaymccarthy/matrix?

hi,

In trying to get the Racket binding for libtcod (a roguelike library) 
working, I've run into the error:

#

test.ss:3:9: tests/eli-tester: standard-module-name-resolver: collection 
not found: "tests" in any of: (#<path:C:\Documents and 
Settings\george\Application Data\Racket\5.0\collects> #<path:c:\program 
files\racket\collects>) in: tests/eli-tester

setup-plt: error: during making for 
<planet>/jaymccarthy\spvector.plt\1\2 (Semi-persistent Vectors)

setup-plt:   test.ss:3:9: tests/eli-tester: 
standard-module-name-resolver: collection not found: "tests" in any of: 
(#<path:C:\Documents and Settings\george\Application 
Data\Racket\5.0\collects> #<path:c:\program files\racket\collects>) in: 
tests/eli-tester

#

The binding's sample requires 'matrix' from Planet, which has a test.ss of:

#lang  scheme
(require  scheme/package
          tests/eli-tester
          "main.ss")

Can someone tell me how to get 'tests/eli-tester' or how to work without 
it? I've thought of downloading everything but test.ss manually but it 
seems like there should be a simpler way?


thanks, George
