When you installed a port with macports the idea was to use as much of the macports for build and runtime dependencies. Over time that became greater and so port install would be slow until you built enough dependancies. It also consumed more storage.
When you installed a port with brew it used as much of the OSX, X11, and XCode installed utilities as possible so it was faster and used less storage. But then you would install an update from Apple and things would break cause of that reliance, things like /usr/bin/perl.
