So, what was the actual error message? What was the kit used to build Qt Creator?
On what platform are you actually on? Insulting doesn't help. Qt Creator 3.1.1
sources should be buildable with Qt 5.3. That is completely independent from the Qt version
Qt Creator was built with (you can even build Qt Creator still with Qt4 and compile your
applications against Qt5 with it).

That doesn't have to do much with Qt versions either. The failed dependency is because
Qt Creator is not binary compatible between minor versions:
http://doc-snapshot.qt-project.org/qtcreator-extending/coding-style.html#binary-and-source-compatibility
so you cannot use plugins compiled against Qt Creator 3.0 in 3.1.

I thought that was exactly what you tried to do.
