For instance, the ppc section of my libc++ guide has the user take the following steps to uninstall the intel-only ports that were required to bootstrap the compiler and then re-install them using the compiler with a ppc slice:

sudo port -v -s -n upgrade --force clang-3.6 universal_archs="i386 ppc
x86_64" configure.compiler=macports-clang-3.6
