Script Libraries

Question

I'm attempting to load the resulting swf of a swc build manually. Due to my particular environment, we have a need to segregate class definitions into swcs (where it makes sense) to remove redundant code from output swfs.
In a nutshell, I'm defining a class (LibA) in a swf that I'm building with compc. I'm compiling it both into swc and directory formats so I can easily extract library.swf from the directory to load at runtime (external linkage) and use the swc to compile out from any swf's built either with Flash CS5 or mxmlc.
LibA.as:
package
    public class LibA
        public function LibA()
            trace("*** LibA()");
Main.as:
package
    import flash.display.Loader;
    import flash.display.Sprite;
    import flash.events.Event;
    import flash.net.URLRequest;
    import flash.system.LoaderContext;
    public class Main extends Sprite
        private var self:Main;
        private var context:LoaderContext;
        public function Main()
            var l:Loader = new Loader();
            self = this;
            l.contentLoaderInfo.addEventListener(Event.COMPLETE, function(e:Event) {
                self.addChild(l.content);
                var liba:LibA = new LibA();
            l.load(new URLRequest("./libs/build/liba.swf"));
I build the swc/directory swc with
compc -output libs/build/liba.swc -include-sources libs/LibA.as -debug=true
and I set the appropriate linkage in AS3 settings in Flash CS5 when building Main (class linked directly to the stage).
Everything publishes without an issue.
However, at runtime I get VerifyError: Error #1014: Class LibA could not be found.
What am I missing here? I want to be able to load and use classes defined within liba.swf from myMain.swf.

If I understand your posting correctly.. then I have a problem with it. Your "correct answer" is based on the assumption that you know what the interviewer meant by "what script libraries are in Oracle?". It also assumes that the interviewer places more worth in copying and pasting the work of others than learning by simply trying something yourself*.
And Mrs Assumption is the mother of the Fubar kids.
The correct response would have been to asked the interviewer to explain what he meant by "script libraries in Oracle".
* E.g. in an interview, I will hold a candidate in much higher esteem if he knows RFC821 because he struggled with UTL_SMTP, versus having copied and pasted someone elses code (from a script library), writing something that worked 1st time around.
In the first instances the candidate shows proper problem analysis skills. In the latter situation, he simply shows he capable of copying others work. The first type of candidate I will be able to assign complex tasks too as he has the tools and mindset to deal with resolving complex problems. The latter type of candidate is a dime a dozen and nothing special - simply pulling a 9 to 5 job without demonstrating any skills worth noticing (or paying extra for).
