Hi Michael,
                       No problem, I understand. I'll keep working on it. 
Thanks for the help so far, couldn't have reached this stage without your 
timely advice!! :-)

FYI, the issue with -framework Carbon being generated into the QtGui.pc is a 
real bug. It happens, even if I generate a build with cocoa 32-bit with no qt3 
support.

I've posted a note on the Qt forum here, describing the bug.

What I can do in the meantime to progress the gr-qtgui build is to manually 
edit the Qt pkgconfig files and replace the reference to Carbon with Cocoa. 

I'll post the results back to the list, if I'm successful.

best regards,
