The capability exists in MacPorts base to do this (by changing the sdk and 
deployment target in macports.conf), but it may not work for some ports. The 
MacPorts base functionality is supported, in that if there is a bug with it, we 
should fix it. The ability to build any given port using this feature is less 
well supported. You could conceivably say it's unsupported, in that I probably 
wouldn't expend too much effort to make this work, since it's such a niche 
feature. If the user can supply patches to make it work, of course we should 
consider incorporating them.

The user wished to build for 10.5 PowerPC on 10.6 Intel. The user may not have 
access to a machine that can run 10.5 to do the build natively.
