This should be simple, but google has failed me (more likely I didn't ask it nicely).

Using FlexBuilder 3, I just added code to do some JSON stuff. When I compile/debug from FlexBuilder everything works wonderful. When I try to compile using MXMLC I get the error "Access of undefined property JSON."

Some details;

In FlexBuilder I am using SDK - Flex 3.5.

The compile command line is:

```
mxmlc -load-externs=report.xml -warnings=false myModule.mxml

```

The import in the module is:

```
import com.adobe.serialization.json.JSON;

```

I suspect it is a library I need to include on the command line, but it eludes me.
