RHEL kdelibs was rebased to 4.14.8 in 7.2, but epel7 libkmahjongg has: Requires: libkdegames%{?_isa} >= %{_kde4_version} As epel7 libkdegames is still at 4.10.5, this results in a broken dependency tree.
Are you sure about this? Installing kmahjongg 4.10.5-1.el7 from EPEL seems to work fine on CentOS 7.2.1511.
Well, it'll be broken when/if libkmahnongg is ever rebuilt
