There are two issues regarding how the gamess-20101001.3.ebuild does its pax markings: 1) instead of calling paxctl directly, it should inherit the pax-utils.eclass and use pax-mark. The eclass has intelligence to take care of the situation where paxctl is not present. 2) The 'hardened' use flag refers to only a hardened toolchain, not to a pax hardened kernel. So the pax markings should not be done unconditionally, removing any "use hardened" tests. Reproducible: Always
Fixed in new release =D
