Photoshop CS2, Mac version, filter does not show

Hello,
I m compiling Dissolve sample plugin for photoshop CS series.
I succeed to compile CS3 and CS4 version since there is a xcode project.
I can see the plugin in the filter menu after I launch photoshop.
It works perfectly.
BUT, as for the CS2 version, I succeeded to compile it by changing CS4 sample project... But I could not get it to show in the filter menu.
The sample project is codewarrior based, so i cannot use it.

I m using Mac OS 10.5 and xcode3.

Any sample project to compile CS2 filter around?

Thanks in advance
