when trying to install the above,I kept getting the message about circular dependencies,and to remove various flags . It didn't seem to matter which flag I restricted ,the dependencies either grew or were less. I eventually found the cure by removing the number tag on qt ie: qt4 > qt. Previousy had even reoved the qt flag ,with no cure so in desperation that's what I did.
Steps to Reproduce:
the circular dependency issue every time
Not too sure whether emerge info is relevant as I have found a way around the problem. I also suspect the problem may arise on my x86 machine as well,but not up to that stage as yet
To workaround this problem install gtk+ without cups first:
USE="-cups -doc" emerge -1 gtk+
