Unable to resolve component to compilation

Question

I am using the FB4 beta 2 with the latest stable build (4.0.0.13875) and am unable to use components within the same library project.  I have created a simple project as an example with two components, Simple and Composed.  They both extend s:Group.
Simple.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
      xmlns:s="library://ns.adobe.com/flex/spark"
      xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300">
     <s:Label text="Hello world" />
</s:Group>
Composed.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
      xmlns:s="library://ns.adobe.com/flex/spark"
     xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300" xmlns:components="components.*">
     <components:Simple>
     </components:Simple>
</s:Group>
Both files reside in the same directory (the components directory).  I cannot even import the Simple class in a script declaration.

I agree, this is strange and may not be directly related to FB4 or the SDK.  I am considering re-installing FB4...
Here is what I do know (I would attach the fxpl if I could):
- this is a flex library project, not an application.  That seems to make a difference.
- the components package does live under the src directory
- I cannot import the class in AS, as if the component simply does not exist
- there is an entry in the flexLibProperties file (and it is correct)
- FB4 autopopulates the component and also provides it in the designer (which leads me to think it is not FB4)
- I am using the standalone version
I am wondering if I inadvertently flipped a setting somewhere, although I don't see what I could switch that would cause components to be invisible.
