I don't know what to do with this bug report. MacPorts isn't designed for picking and choosing build architectures on a port-by-port basis like that. Use the same build_arch and universal_archs settings (in macports.conf) for building all ports in a given MacPorts prefix and don't override them on the command line.

feel free to close it when

[ryandesign (Ryan Carsten Schmidt)]

If you want to build things for ppc on Snow Leopard, either for some ports (which as I say is unsupported and fraught with peril) or for all ports, then set build_arch to ppc and add ppc to universal_archs (so universal_archs x86_64 i386 ppc). If you change the value of universal_archs, you should manually rebuild (or uninstall and reinstall) any ports that were already built universal with the previous set of universal archs. (MacPorts doesn't expect you to change it after ports have been installed.)
