Does your merge() function serve the same purpose as Elias's merge.rb  
script? I mean, I'm happy to see something like this in MacPorts  
base, implemented in tcl, as opposed to ruby.

backup() and lipo() were other functions that were added at some  
point to assist in creating universal versions of ports that don't  
build universal all at once. Does your merge() function obsolete these?

Granted we need more universal support in base, but we should  
coordinate things amongst ourselves, not duplicate effort, and not  
create different ways of doing the same thing.
