Installing MacPorts

Post install text:

Congratulations, you have successfully installed the 
MacPorts system. To get the Portfiles and update the 
system, run:

sudo port selfupdate

Please read port(1) and the MacPorts Wiki at 
http://trac.macports.org/ for full documentation.

Stray sources might have been left in the legacy 
/opt/local/var/db/dports directory after this upgrade,
which moved most of what it could to 
/opt/local/var/macports, so you might want to look in 
the former and cleanup manually.
