AIR and PixelBender compatibility

Question

Already posted a question in the PixelBender fourm, but
thought perhaps someone has encountered the same issue here in the
AIR forum.
In one of my classes I have
//CODE START
package filters
import flash.display.Shader;
import flash.filters.ShaderFilter;
public class MyFilter extends ShaderFilter
//CODE END
I get the following error when compiling in the IDE
1017: The definition of base class ShaderFilter was not
found.�
I figure this MUST be a class pathing issue.
Can someone help? Is there some additional pathing beyond the
default must be set up in Flash 10 CS4 when targeting AIR1.5 and
using PixelBender filters?
These are all my pathing settings
Application or Global path settings
Flex SDk path
$(AppConfig)/ActionScript 3.0/libs/flex_sdk_3/
and
Library path
$(AppConfig)/ActionScript 3.0/Classes/
These are my publish class path settings
Source path (2 entries)
../classes
Library path (2 entries)
$(AppConfig)/ActionScript 3.0/libs
$(FlexSDK)/frameworks/libs/flex.swc
External library path (1 entry)
