It worked for me too, thanks !

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
