If you need regular output, I'd just recommend running macports in
verbose mode, i.e. port -v install …

This will generate more output, but not nearly as often as the progress
bar updates, it will help you figure out what went wrong if the build
fails, and it will correctly abort if a build appears to hang for
whatever reason.

The code in src/port1.0 runs in a Portfile context. The code in
src/macports1.0 allows using MacPorts as a library. Code that's for the
user interface is in src/port.

If you follow the code path and variables, you'll see that
src/port/port.tcl defines the functions, passes them to
macports1.0/macports.tcl in the ui_options argument of mportinit, and
[1] passes them into the Portfile Tcl interpreter, where you'll see them
invoked as ui_progress_generic from src/port1.0.

If you want to modify the progress bar layout, you thus need to change

I always just used printf debugging. I'm not sure whether there are
better tools these days.
