It is. This box tells the compiler where to find _your_ private  
framework directory. Since you placed SDL.framework into  
/Library/Frameworks, which is the standard location, you shouldn't have  
any problem with this, anyway. What you really want is to tell the  
compiler to _link_ with the framework. Either drag the framework in way  
down, under "Frameworks & Libraries", or select "Add Frameworks…" from  
the "Project" menu. A third way would be to specify "-framework SDL" in  
the linker settings.
Note that all this still doesn't change your _header_ search path: if  
you do #include "SDL.h", you'll have to add  
"$(LOCAL_LIBRARY_DIR)/Frameworks/SDL.framework/Versions/A/Headers" to  
your header search paths. #include'ing "SDL/SDL.h" should work fine,  
though I haven't verified this.
  The resulting app first searches for the framework in your .app bundle  
(under "Frameworks", "PrivateFrameworks" and "SharedFrameworks", just  
as documented in the link from my last mail), and if it's not there, in  
/Library/Frameworks, /Users/yourusername/Library/Frameworks and  
To have Project Builder automatically copy the Framework to your .app  
bundle, add a new "Copy files" build phase ("Project/New Build  
Phase/New copy files build phase"). You seem to have an active  
selection in the "Build Phases" list GUI to do this. Under "Where"  
select "Frameworks", no subpath; drag the framework bundle into the box  
down there.

I guess not. This would, of course, also defeat the whole purpose of  
this exercise: to still be able to easily exchange (e.g.) the  
SDL.framework with a newer version, on a per-app basis, if needed.
If you really want to do this, you could look into "Umbrella  

HTH, and sorry to Sam, who has to approve of all my mails, because my  
"From" header is getting garbled by the mail server :-(
