"Missing URL" error when used in Node.JS

[arv]

What steps will reproduce the problem?

1. Checkout http://github.com/aikar/traceur which I wrote a loader to middleman module loads to run through traceur
2. delete traceur folder and recheckout from SVN (I commented out the error in traceur/src/semantics/symbols/ModuleSymbol.js)
3. run node test.js
4. Witness "Missing URL". For bigger projects it spams alot more.

What is the expected output? What do you see instead?
No error

What version of the product are you using? On what operating system?
latest trunk as of 9/19/11

Please provide any additional information below.

NOTE: To get traceur to work with node.js I had to disable the FreeVariableChecker like so:
traceur.semantics.FreeVariableChecker.checkProgram = function() {}

This is due to Traceur blowing up saying module was not defined.

also, to assist debugging I threw in an exception to get a stack trace:

A couple of notes.

Make sure you are passing in a url to the Project constructor:

var project = new traceur.semantics.symbols.Project(document.location.href);

Secondly, you can now set traceur.options.freeVariableChecker to false. You might also want to disable the validator to speed things up. See options.js for more info.

Do you still think there are things that need to change in traceur to better handle this?
