Build 4.6

Hi,

I have just downloaded Flex 4.6 framework, and I cannot build the sdk.

When I run ant main, I've got a lot of errors :

...
////////////
    [compc] ^
    [compc]
    [compc] C:\FlexSDK\4.6.0\frameworks\projects\framework\src\mx\core\ILayoutEl
ement.as(29): col: 41 Error: Interface IEventDispatcher was not found.
    [compc]

rectionElement.as(1): col: 1 Error: The definition of base class Object was not
found.

When I build 4.5.1, I have no error and everythink works fine.

Is there a difference in 4.6, should I define a new environnment variable or add an argument to the ant command ?

Thanks in advance.
