Affected packages (only games-action/openclonk, AFAICS) should use ISC instead, and licenses/CLONK-source should be removed.
Removed: CLONK-source Log: rm, because CLONK-source is a duplicate of ISC + 12 May 2012; Julian Ospald <hasufell@gentoo.org> openclonk-5.2.2.ebuild: + fix licenses wrt #415645 thanks
