 > I think I'm going to need more specific instructions before I can test
 this on my machine.  I've followed the instructions from here:
 http://guide.macports.org/#installing.macports.subversion and here:
 https://trac.macports.org/wiki/Migration (By the way, did I need to
 actually delete the old MacPorts from the package at any point?  I just
 did sudo make install "on top" of whatever was there before.)  After "sudo
 make install" is when I added those three lines to macports.conf, is that
 right?

 reinstall all my ports, but I'll wait for confirmation before starting
 that long process.

 You should try asking for help with things like this on the macports-users
 mailing list.

 sudo make install "over" the package installed bits is fine.

 You should do 'sudo port -v -f uninstall installed' and start from scratch
 with the updated config.
