This means your Qt 5 wasn't compiled QtDeclarative (repository qtquick1), or that it wasn't properly installed.

Check that you've e.g. a $HOME/src/cpp/qt5/qtbase/mkspecs/modules-inst/qt_lib_declarative.pri file. If not, try to rebuild libQtDeclarative by running 'make sub-qtquick1' in your qt directory.

No.

> PS: tried make -i which will build a version but that one fails to run with: 
> Failed to load core: Could not find 'Core.pluginspec' in /home/rkrause/src/cpp/qt-creator.git.qt-5.0.release
>/lib/qtcreator/plugins,/home/rkrause/.local/share/data///QtProject/qtcreator/plugins/2.6.81

There are some compilation steps that automatically generate/copy the pluginspec files to the target directory. This fails e.g. if your source directory is tainted / contains an old build.
