How to add Actionscript 3 fl.controls (UIScrollBar) on Linux

How would one go about adding fl.controls.* to AS3 projects developed under Linux?

Apparently it is not part of Flex 3SDK for Linux (which is what I am using to compile) or maybe it is and I am not importing it correctly开发者_如何学Go..I downloaded this SDK last March, maybe time for update?

Looking at Adobe Official Docs for fl.controls does not mention that this library is somehow restricted.

In particular, I was looking for fl.controls.UIScrollBar type of functionality

I am using MiniBuilder to edit.

Packages starting with fl.* are part of (and only available in) the Flash authoring tool (Adobe CS3/4) and cannot be imported to Flex projects. Check this answer
