My Mac accumulated a lot of installed ports that I may not need when reinstalling it soon.
I want to only install those packages which I know I'm using, but to filter them out of the huge list of
port list installed is impractical.
I'm looking for a way to out put a list of just those installed packages which don't have any other package depending on them. Better yet, I'd love to have a way to visualize the dependencies.
Any ideas on how to accomplish either one?
