Error message: "QML module not found (...)"

Starting with QtC 4.6.0 version for its QBS modules, I see the following message: "QML module not found (...)"
See pict. at attachment.
As an example, I add one of my files (qbsutl.js) for which this message appears.
The remaining modules, for which this message also appears, can be found here:
