I replaced it with:

if {[lsearch [get_canonical_archs] ppc] != -1 || [lsearch [get_canonical_archs] ppc64] != -1} {
    # Until llvm better supports darwin/ppc, the only C++11 compiler for ppc is gcc
    compiler.whitelist macports-gcc-4.7
} else {
    compiler.blacklist gcc-4.0 gcc-4.2 apple-gcc-4.2 llvm-gcc-4.2 macports-llvm-gcc-4.2 {clang < 300}
}
