Yes, this is really neat and is usually the way to create universal 
binaries. In Google Summer of Code 2007 was a project to implement this 
in base, but it did not complete. The final result which came out is 
proc merge in port1.0/portutil.tcl. It actually does all the stuff 
needed to merge multiple trees together with lipo.

Missing is a way to run the port phases multiple times for all requested 
platforms and then call proc merge.
