Is MacPorts Universal?
MacPorts works on both Intel- and PowerPC-based Macs, but, by default, the ports you install will be compiled only for the architecture you’re currently running on. This means that if you migrate from, say, a PowerPC Mac to an Intel one and use Migration Assistant to copy your data to the new machine, you should reinstall all your ports on the new machine to rebuild them for Intel. See the Migration link in the previous question. For many ports, there’s now an alternative: select the +universal variant when you build each port, and MacPorts will create universal binaries that work on multiple processor architectures. The set of architectures is controlled by the universal_archs setting in macports.conf. Using +universal can allow you to run ports which do not build for your preferred architecture alongside those that do. For example, the wine port only builds for i386, but shares many dependencies with ports that can build for x86_64. On x86_64 hardware, the dependencies can be built w
