Description of problem: The Fedora version of Gcompris-QT has an unmet soft dependency for qml-box2d (see Fedora bug https://bugzilla.redhat.com/show_bug.cgi?id=1673970). This causes some activities within Gcompris to not be included. Adding qml-box2d to the Fedora repos will allow Gcompris to be rebuilt with these activities. qml-box2d can be found here: https://github.com/qml-box2d/qml-box2d/
This place is to review package, not request them. If you want to package it, post your SPEC and SRPM.
There doesn't appear to be anything to do here.
