MacPorts uses /opt/local by default. 

/usr/local is for software you install manually. On Intel Macs, Homebrew takes over this location. Attempting to configure MacPorts to use this location will produce a loud warning explaining that we don't recommend using that location. 

Having Homebrew and MacPorts installed on the same computer will cause problems and is not recommended. Neither is installing software to /usr/local manually.
