Perhaps MacPorts should consider separate binary repos for 10.4/10.5 and 10.7/10.8. If all
of the binaries are built on Snow Leopard, this prevents those binary MacPorts packages from
being built against the fortified 10.7 SDK and linked with -pie so that those executables won't
leverage ASLR on Lion. This really does represent a security regression introduced by MacPorts
2.0.4.
