the fact that it still links to Carbon, doesn't mean that it is a  
"Carbon application" :).
Actually it is also linked to Cocoa (/System/Library/Frameworks/ 
AppKit.framework/Versions/C/AppKit).
And also *not everything* of carbon is deprecated for 64 bit. There  
are lots of API calls that one still can (and must!) do through the  
carbon API. But (most of?) the Carbon GUI API is gone for 64bit. A  
hint that this is Qt/Cocoa is hidden in the fact that it links against  
the objective c base library (/usr/lib/libobjc.A.dylib).
