A/ qt-creator conditionally depends on dev-vcs/git which, in turn, conditionally depends on dev-lang/tk. B/ building qt-creator +git enables a couple of menu options such as Tools/Git/Git Tools/Gitk which, if selected, will trigger an error (Cannot launch "/usr/bin/gitk") if dev-vcs/git was built with default use flags (-tk) => I suggest the PDEPEND on dev-vcs/git in qt-creator's ebuilds to be changed to a PDEPEND on dev-vcs/git[tk]. Reproducible: Always
I can guess a tk dependency would be quite unwelcome by most people using qt-creator with git integration. And since everything else works because all core git commands do not depend on tk, I'm not going to add the USE dep.
