Umm... what do I do after the:
git reset --hard 74c0ee1ffed5d3dc9afe5f21fd62cb351253ffe9
to get the code so I can make a fresh set of tarballs? Do I need a git pull or git clean and submodule init?
Just start building.
I wonder whether you have incomplete sources. Last week that happened to me. Eventually I got all modules updated and have been okay since.
cd to tdelibs in your GIT sources and perform a git pull. Likewise with tqtinterface. Not saying that will solve anything, but you should see messages whether you're up to date or not.
