[Qt-interest] Show dependencies on Mac

[Konrad Windszus]

Instead of the otool command, you could also use the application  
MacDependency (http://macdependency.googlecode.com) which shows the  
complete dependency tree as well as the exported symbols in a nice  
Cocoa Interface. Although not programmed in Qt (anymore) it may be  
helpful to the Mac developers. I wrote this tool, because there was no  
Mac equivalent to the DependencyWalker on Windows.

@Qt employees: Maybe you also want to add a link to MacDependency to  
the Mac Deployment section in the documentation (http://doc.trolltech.com/4.5/deployment-mac.html#additional-libraries 
)
