Comment (by ryandesign):

 Yes, MacPorts installers have always (since the introduction of Macs witth
 Intel processors) been built universal.

 Instead of specifying `-arch` flags manually within `CC` and `CXX`, use
 the configure argument `--with-universal-archs="ppc ppc64"`.

 If that fails, attach the config.log so we can see why it failed.
