So you've set universal_archs incorrectly in your macports.conf. Likely, you upgraded from an old version of MacPorts and/or an old OS (Leopard or earlier) where i386 ppc was the correct value for universal_archs. It's not anymore. Update your macports.conf. See:

https://trac.macports.org/wiki/Migration#Updatemacports.conf

Then forcibly rebuild libiconv (and other ports that are installed with the universal variant).
