Comment (by kencu):

 Jeremy set up a few ports to build universal by default, to allow the
 buildbot to have the right binaries always available.

 On 10.6 and up, this is fine, and should not change.

 For 10.4 and 10.5 (and 10.6 on PPC / Rosetta) macports current default
 universal archs don't match what the non-system gcc (and clang) compilers
 can build. I asked three or four years ago for the universal arches on
 these systems to be changed to what the toolchain could build, but this
 request was declined vociferously.

 So you're stuck. You could put forth a PR to disable universal building of
 libunwind and libcxx on such systems if you like.
