It looks like a simple enough change to me. But I'm not familiar  
enough with base to understand why the [option os.arch] syntax was  
used to read the variable instead of ${os.arch} so I don't know  
whether perhaps that syntax might be needed now in some places to read  
configure.build_arch.

You could create a second MacPorts installation in a different prefix,  
and set build_arch to i386 in macports.conf, and see if i386 works  
properly.
