My expectation is that on a G3, G3 code will be generated, so I'm not sure why he's seeing this problem. Overriding portfile options like configure.optflags at the command line can be a useful troubleshooting tool, but it is not something users are expected to need to do on a regular basis. Let's perhaps wait and see what the actual architectures of the files in question are, and analyze the build log of the one that has the wrong arch, before we recommend changing any flags.
