Ok.

You can use whichever method works best for you in a particular situation. I usually clean a port and start over when I've made a change during development, but sometimes, especially for ports that take a long time to build, I edit the statefile or find other ways to continue the build without cleaning. For example, if a port fails during the destroot phase, I might be able to fix it by just editing the destroot directives in the Portfile, deleting the destroot directory, and then retrying the installation and using the -o flag to prevent MacPorts from cleaning the work directory.

Indeed, if a port is already installed with the same variants, port install doesn't do much. (If it's installed but with different variants, then it would be installed with the new variants.)

Not sure what you mean by "do all steps from $(port work munin)/.macportsmunin.state". The statefile records the steps that have already been completed. If you port install, MacPorts will resume from the next not-yet-completed step.

I guess I'm not entirely clear on what the problem is that you're trying to solve, so it's hard to suggest solutions.

That's correct.

The rebuild command is:

sudo port -ns upgrade --force
