hi,
im using the sparke frameworks.
Ive done all the procedures to link end "new copy build" etc etc..
the problem is that during the Debug version, its works fine (the 
compiler copy all the frameworks inside the .app),
during the Release I get the error:

Checking Dependencies

pbxcp: warning: couldn't strip: /Users/Lynx/SDK/AutoRender/build/

I dont really understand...
How can I fix this?

tnx
