Personally, I don't use qt5.git,   but check out the repository that I need.
(I clone separately qtbase, qtxmlpattern, and qtdeclarative)

I think that your problem is that your versions of qtbase and qtdeclarative 
did not match.
All the module needs to be on the same branch.  So if you checkout qtbase 
stable,  you also need to checkout qtdeclarative stable.

Notice that qt5.git is often lagging behind.  (But there are plans to change
