MacPorts supports any combination of architectures you define in the universal_archs variable in macports.conf.

Some ports have problems building 3-way universal and will either fail (because nobody tried it yet) or will only build 2-way universal (because somebody tried it, noticed it, and told the port about it).

MacPorts does not support cross-compilation for an earlier OS version. (Ports you compile on 10.6 can't necessarily be used on 10.5.) This feature used to exist but was removed because it did not work reliably for most ports.
