Not sure why Flex Builder isn't figuring it out by itself, but you can manually set the source path of any swc on the library path (you have to do this for each project):

• Right-click on the project, Properties
• Flex Build Path property page
• Library Path tab
• Expand the "Flex 4.0" node at the top, then expand the swc that you want to attach source to
• Double-click the "Source attachment" line, and specify the root dir of the source, e.g. C:\...\mysdk\frameworks\projects\framework\src
