Actually, if both machines were running the same major version of Mac  
OS X, I wouldn't have thought anything would need to be reinstalled,  
since MacPorts will build 32-bit software by default, even on a 64- 
bit machine. And even so, 32-bit software should work fine on 64-bit  
machines.

port selfupdate never updates ports; it only updates MacPorts base if  
a newer version is available, and it updates your port definitions.

port outdated only shows a port as outdated if a newer version of it  
is available. It might be nice if it were possible for port outdated  
to know for example when your ports were built with an older version  
of Mac OS X or Xcode or on a different processor architecture (e.g.  
PowerPC vs. Intel) and to flag these as needing a rebuild too, but  
that capability does not exist in MacPorts at this time.
