Edit macports.conf and set universal_archs to a value that is two or more valid architectures for your OS version, or comment that line out (by putting a # in front of it) to let MacPorts do so by default.

Setting build_arch to more than one architecture is invalid. Set it to the single architecture that you want to build for when not building universal, i.e. x86_64.

This is the correct setting for universal_archs on your OS version. Having it set to this value should prevent the warning you see from appearing.
