Apple gcc 4.2.1 became available on Leopard, but was not the default until Snow Leopard. In Leopard and Tiger, the default compiler is Apple gcc 4.0.1. There isn't a switch in MacPorts to tell it to globally use a different compiler; individual ports decide what compiler they should use (which is usually the default one on the given version of Mac OS X, unless there's a specific reason why that won't work).
