It worked for me too, thanks !

@biaspoint I am pleased you have your situation sorted. Purely OOI, because I like shell scripting, why did you bother to put the xargs into your command when dpkg -l | grep qt | awk '{print $2}' would deliver the same result? :) | xargs -n1 echo is a bit of a no-op?

Since the patch has already been integrated you can also build from the current 5.5 branch from git
